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.
