RESULT AND DISCUSSION (3/3)

8

Threshold power for each stokes:

•1st Stoke = 19.03 dBm

•2nd Stoke = 21.78 dBm

•3rd Stoke = 21.85 dBm

•4th Stoke = 21.91 dBm

•5th Stoke = 21.98 dBm

CONCLUSION

New design of multiwavelength DBR Brillouin effects using HNLF with linear cavity was demonstrated.

The number of Stokes lines obtained depends on the Brillouin pump power.
