WELCOME TO ISUPTW 2018
Welcome to the 9th International Symposium on Ultrafast Phenomena and
Terahertz Waves (ISUPTW 2018). ISUPTW, an international symposium, is
devoted to strengthening the collaboration among worldwide researchers and
promoting the development in ultrafast and terahertz science and technology.
The biennial symposium, initiated in 2002, has been held in Beijing, Shanghai,
Nanjing, Tianjin, Xi'an, Wuhan, Shanghai and Chongqing. It brings together
scientists, technologists, and students from more than 10 countries and typically
hosts 150-300 participants.
This year, the conference will be
held in Changsha from 23rd to 26th
April at Empark Grand Hotel
Changsha, organized by National
University of Defense Technology
(NUDT) and Optical Society of
America (OSA). We received 190
abstracts from 13 countries and
pushed our technical program to
work hard to complete the peer
review response on time. We thank all committees for their suggestions and
recommendations and all reviews for their good work. We hope you will enjoy the
technical program of this conference; we have numerous exciting talks lined up as
well as exhibits by many of the active companies in the field.
We would also like to invite you to enjoy and explore Changsha’s unique cultural
characters and beautiful cityscape.
Situated in the river valley along the lower reaches of the Xiang River, Changsha is
the capital city of Hunan Province. The recorded history of Changsha can be
traced back 3,000 years. Tomb relics from the primitive periods witnessing the
earliest human activities have been discovered in this region. During the Spring
2
and Autumn Period (770 B.C. - 476 B.C.), the area developed into an important
town within the State of Chu, (one of the seven warring states that existed before
China's unification by Emperor Qin). After Emperor Qin (the first feudal emperor in
China's history) unified the country, the town was set up as a county and later
became the capital city of a state in the early Han Dynasty (206 B.C. - 220). The
tomb excavation site of Mawangdui found in the eastern suburb of the city is a
family graveyard from that period. The most fantastic historical relic should be the
well-preserved mummified remains of
a Western Han Dynasty woman
excavated from the tombs. Some of
thousands of relics unearthed include
silk products, paintings, lacquer works,
potteries, bamboo slips used for
writing, weapons and herbs, all of
which are exhibited in Hunan Provincial
Museum.
In the dynasties that followed, the city experienced several expansions and during
China's Qing Dynasty (1644-1911), it has developed into the political, economic
and cultural center of Hunan Province.
Although not as ancient a capital city
as Beijing, Nanjing or Xian, Changsha
also has rich historical heritages
including old wall remains, tomb sites,
religious temples and buildings. What
earns the city its reputation among
tourists are two things. One is a great
man in China's recent history,
Chairman Mao Zedong and the other
is Yuelu Academy, a time-honored academic school perched on the scenic Yuelu
Mountain. Originally built in 976 during the Song Dynasty, the academy school
survived through the Yuan, Ming and Qing dynasties and is considered to be the
cradle of Huxiang Culture. (simply means the culture school in Hunan Province)
3
The village of Shaoshan, about 130
kilometers south-west of Changsha is
the hometown of Chairman Mao
Zedong. Today, the village has become
a memorial place for Chinese people to
remember this extraordinary man.
People erected a statue of the
Chairman and have preserved the
houses he lived as a tourist site. A
museum and other memorial spots in the scenic area create a kind of solemn
atmosphere. Many Chinese come to pay respect and visit here during the
memorial days.
In addition, the city was home to other
revolutionary leaders including Liu Shaoqi,
Huyaobang and former Chinese prime
minister, Zhu Rongji. Therefore, it acts as a
good place to learn more about China's
recent history.
Changsha people boast to be the best
gourmand of China and here people
spend a lot of time eating. Xiang Cuisine
is one of the Eight Cuisines in China and
has a fine and delicate appearance and
a hot & sour taste and the heavy and hot
taste is an equal competitor to the spicy
food of Sichuan. Street dining and
restaurants in the city make every visitor's
mouth hot. No matter the featured
snacks - 'Stinky Tofu' and 'Sisters'Rice
4
Balls' in Huogongdian (Fire Palace) or the
famous spicy shrimps at Nanmenkou, the
many types of delicious local food will
not disappoint any guests.
Changsha people are also renowned for
their acting and have created various
traditional folk art performances of their
own including the local operas,
storytelling, drum opera, acrobatics and other dramatic styles. Everyone can feel
their hospitalities and enthusiasm by their vigorous dances. Today, most of the
entertainment houses in the city
present dynamic and entertaining
performances featuring a blend of the
traditional essence and the modern
flare. The neon lights of KTV squares,
disco parlors, clubs and dancing
squares illuminate the city at night.
Dotted with all sorts of bars and pubs,
Jiefang Xilu, although not as
prosperous as Sanlitun Pub Street in
Beijing, has its own styles. Romantic and quiet bars, dynamic show bars, teahouses,
western style restaurants...People of all ages can find their ideal place to spend
their leisure time.
Welcome to ISUPTW 2018. May you have a fantastic time in Changsha!

Progress in ultrafast terahertz scanning tunneling microscopy
F.A. Hegmann, University of Alberta, Edmonton, Alberta, CANADA
The ability to directly probe ultrafast phenomena on the nanoscale is essential to our understanding of
excitation dynamics on surfaces and in nanomaterials. Recently, a new ultrafast scanning tunneling
microscope (STM) technique that couples terahertz (THz) pulses to the scanning probe tip of an STM was
demonstrated (THz-STM), showing photoexcitation dynamics of a single InAs nanodot with simultaneous 0.5
ps time resolution and 2 nm spatial resolution under ambient conditions. Operation of THz-STM in ultrahigh
vacuum now makes it possible to spatially-resolve subpicosecond dynamics of single molecules and silicon
surfaces with atomic precision. This talk will discuss how THz-STM works, recent progress, and how THz-STM
can provide new insight into ultrafast dynamics on the atomic scale, which is essential for the development of
novel silicon nanoelectronics and molecular-scale devices operating at terahertz frequencies.
Frank Hegmann received his PhD in Physics from McMaster
University in 1994 and then worked as a postdoctoral researcher
at the Center for Terahertz Science and Technology at the
University of California, Santa Barbara. In 1997, he started as an
assistant professor in the Department of Physics at the
University of Alberta studying ultrafast dynamics in materials
using time-resolved terahertz (THz) pulse spectroscopy. He is
currently a Professor in Physics and AITF Strategic Chair in
Terahertz Science and Technology with research interests in THz
pulse spectroscopy of nanomaterials, ultrafast imaging, ultrafast
THz-STM, terahertz nonlinear dynamics, and biological effects of
intense THz pulses.

The development of terahertz (THz) source and modulation facilitates a wider variety of applications. This talk
addresses our recent researches on THz sources based on THz parametric oscillator and difference frequency
generation and proposes a novel modulation technology that combines the modulation of both the THz
sources and devices. The works of THz applications in biomedical diagnostics by transmission imaging,
attenuated total reflection imaging and metamaterial based biosensors are described as well, followed by
summarization of the recent progress and prediction of the future trends of THz technology.
Jianquan Yao, member of Chinese Academy of Science, professor
of Tianjin University, is engaged in the researches on nonlinear
optics, physics and technology of laser and THz, and micro-nano
optoelectronic materials. He has served as a visiting professor in
Stanford University, Princeton University, University of
Pennsylvania in USA, and some other universities in UK, France
Germany, Russian, Hong Kong and Taiwan. Professor Yao’s major
achievements are on the laser and optical frequency conversion
technology. He presented and developed the theory and method
of precise calculation of the optimum phase matching for three
wave interactions with nonlinear optical biaxial crystals. His
papers were named “Yao and Fahlen Technology”. He advanced
“Gaussian like distribution” of laser resonant theory. He
developed the theory of laser frequency doubling under high
conversion efficiency and new method with quasi-CW pumping.
He developed an intracavity frequency doubled Nd:YAG laser
whose output power was up to 150 Watts, and this laser source was used to establish laser three dimension
scanning photography system. He invented the dye and Titanium sapphire tunable laser systems pumped by
quasi-CW green laser source. He established a quasi-CW pumped—tunable laser technical system, making
important contributions to the development of the new solid-state laser and tunable laser technologies.
Recently, he focuses on high power laser diode pumped solid state laser, tunable laser, frequency conversion
by quasi-phase matching technology using periodical poled crystals for SHG and OPO, as well as THz wave
generation by DFG and TPO and some other nonlinear optical methods. He was awarded Second Prize for
National Invention et al. He published three books: “Nonlinear Optical Frequency Conversion and Tunable
Laser Technology” (Science Press, 1995), “All Solid State Laser and Nonlinear Optical Frequency Conversion
Technology” (Science Press, 2007), and “Nonlinear Optics and Solid-State Lasers: Advanced Concepts,
Tuning-Fundamentals and Applications (Springer Series in Optical Sciences, 2012). He was elected Member of

Ultrafast light manipulation using photonic micro/nano-structures
Qihuang Gong, Jianjun Chen, Zheng Chai, Hong Yang and Xiaoyong Hu
State Key Laboratory for Mesoscopic Physics, Department of Physics,
Peking University, Beijing 100871, P. R. CHINA
Micro/nano photonic structures permit remarkable control of the propagation of light. The micro/nanoscale
ultrafast light manipulation paves the way for the realization of various nanoscale integrated photonic devices,
which construct the essential basis of ultrahigh-speed and ultrawide-band information processing chips.
Moreover, for practical chip-integration applications, several significant features, including on-chip trigger,
ultrafast response, ultralow energy consumption, and wideband (or multiple-wavelength) operation, are
stringently required.
In this presentation, a selection of recent results will be presented.
we realized an ultrafast, ultralow power, on-chip-triggered 2x2
all-optical switch with multiple operating wavelengths based on
plasmon–photon hybrid nanostructures coated nonlinear
multi-component nanocomposite material formed directly in
integrated photonic circuits. Low threshold pump intensity of 450
kW/cm2, fast response of 63 ps, and multiple operating
wavelengths were realized simultaneously. An ultralow-power
all-optical logic data distributor with dual address bits is also
realized, based on a large nonlinearity enhancement occurs in the
nanocomposite material through resonant excitation via an
upconversion radiative-transfer process, which ensures an
ultralow operating threshold control intensity of 10 kW/cm2. An
ultrafast response time of several picoseconds is simultaneously
maintained based on structural defects inducing ultrafast decay of
excited-state carriers. Based on tunable Fano resonance or PIT of metallic nanostructures, ultrafast
modulations on light transmission were also demonstrated. Moreover, ultracompact plasmonic devices
including SPP unidirectional generator, splitter and others were experimentally demonstrated.

Information Metamaterials and Metasurfaces
Tie Jun. Cui, State Key Laboratory of Millimeter Waves, Southeast University, Nanjing,Jiangsu, CHINA|
Metamaterials are traditionally described by effective medium parameters due to subwavelength scales
of unit particles. The continuous nature of the medium parameters makes the traditional metamaterials
behave as analog metamaterials. Recently, the concept of coding metamaterials or metasurfaces has
been proposed, in which metamaterials are characterized by 1-bit digital coding particles of ‘0’ and ‘1’
with 180° phase difference, or 2-bit digital coding particles of ‘00’, ‘01’, ‘10’, and ‘11’ with 90° phase
difference, etc. It was demonstrated that the electromagnetic waves can be manipulated by changing the
digital coding sequences. The coding particles provide a link between the physical world and digital
world, leading to digital metamaterials and even field programmable metamaterials, which can be used
to control the electromagnetic waves in real time. The digital coding representation of metamaterials or
metasurfaces allows the concepts and signal processing methods in information science to be introduced
to the physical metamaterials, realizing extreme controls to the electromagnetic waves, such as Shannon
entropy, convolution theorem, and addition theorem. Such studies set up the foundation of information
metamaterials and metasurfaces. In this manner, metamaterials are not only the effective materials, but
can also be real-time information processing systems (e.g. new-concept radar, programmable imaging
and hologram, and new-concept communication systems). In this presentation, the coding, digital, and
field programmable metamaterials and metasurfaces are systematically introduced with particular
emphases on recently new developments. The future trend of information metamaterials is also
predicted.

CEP-Stabilized Few-Cycle Laser Pulses Based on Supercontinuum from Gas and Solid Media
Kun Zhao,Beijing National Laboratory for Condensed Matter Physics, Institute of Physics, Chinese
Academy of Sciences, Beijing, China
Carrier-envelope phase (CEP) stabilized few-cycle laser pulses have important applications in high-order
harmonic generation (HHG), coherent light synthesis, and isolated attosecond pulse generation in the
extreme-ultraviolet(XUV) band. Up to now, few-cycle laser pulses were generated from gas-filled
hollow-core fibers. However, this scheme suffers a large loss. In this talk, we report our recent progress
on generation of few-cycle laser pulses toward higher energy. With input pulses of 35 fs and 5 mJ at 1kHz,
6.3fs/1.8mJ and 6.7fs/2mJ laser pulses were generated from helium- and neon-filled hollow-core fibers
respectively. To explore for higher pulse energy, we employed a set of thin solid plates to replace the
hollow-core fiber for spectral broadening. Driven by 0.8-mJ, 30-fs laser pulses, 0.7-mJ white light was
obtained through 7 thin silica plates with a thickness of 0.1 mm, corresponding to an efficiency of 87.5%.
Our analysis showed both self-phase modulation and self-steepening played major roles in the
supercontinuum generation. With such an octave spectrum from 450 nm to 980 nm, CEP was measured
and locked directly by an f-2f interferometer. HHG experiments were performed as the CEP was tuned
from 0 to π/2, the cut-off of the observed XUV spectrum changed from continuous to discrete, indicating
that the CEP was successfully locked and controlled.TuG5 15:00

of most metals, it is hard to realize a strong confinement of SPPs although a propagation loss could be
sufficiently low. Here we introduce the recent work from terahertz surface waves to spoof SPPs based on
metasurfaces.

Ultrafast Light Manipulation Using Photonic Micro/Nano-Structures
Qihuang. Gong, Peking University, Beijing, BEIJING, CHINA|
Micro/nano photonic structures permit remarkable control of the propagation of light. The
micro/nanoscale ultrafast light manipulation paves the way for the realization of various nanoscale
integrated photonic devices, which construct the essential basis of ultrahigh-speed and ultrawide-band
information processing chips. Moreover, for practical chip-integration applications, several significant
features, including on-chip trigger, ultrafast response, ultralow energy consumption, and wideband (or
multiple-wavelength) operation, are stringently required.
In this presentation, a selection of recent results will be presented. we realized an ultrafast, ultralow
power, on-chip-triggered 2x2 all-optical switch with multiple operating wavelengths based on
plasmon–photon hybrid nanostructures coated nonlinear multi-component nanocomposite material
formed directly in integrated photonic circuits. Low threshold pump intensity of 450 kW/cm2, fast
response of 63 ps, and multiple operating wavelengths were realized simultaneously. An ultralow-power
all-optical logic data distributor with dual address bits is also realized, based on a large nonlinearity
enhancement occurs in the nanocomposite material through resonant excitation via an upconversion
radiative-transfer process, which ensures an ultralow operating threshold control intensity of 10 kW/cm2.
An ultrafast response time of several picoseconds is simultaneously maintained based on structural
defects inducing ultrafast decay of excited-state carriers. Based on tunable Fano resonance or PIT of
metallic nanostructures, ultrafast modulations on light transmission were also demonstrated. Moreover,
ultracompact plasmonic devices including SPP unidirectional generator, splitter and others were
experimentally demonstrated.
