Stimulated Mandelstam-Brillouin scattering

[Alexey Alexey Alexey]

Good day!
Can you please tell me if optisystem has the ability to simulate the tension of an optical fiber and the effect of temperature on an optical fiber? Namely, I would like to see how the temperature and tension of an optical fiber affect Stimulated Mandelstam-Brillouin scattering, but I could not find such a possibility in optisysytem (the spectrum did not change when the temperature in the optical fiber changed).

Dear Alexey,
OptiSystem Optical Fiber components doesn’t support temperature dependence. However, you may place an FBG sensor in front of the fiber to study the effect of temp and stress on the performance of the fiber experiencing Brillouin effect. The FBG center wavelength is going to shift due to stress, then it will propagate in the fiber and experience SBS effect that is different. This can be clear if you can load wavelength dependent Brillouin gain data to the component properties popup window in the Enhanced tab. The data structure should follow
1540 42e-12
1550 45e-12
1560 46e-12

Regards,
Ahmad
