Hi, I am trying to use the TWLM model in Lumerical Interconnect as an SOA with saturable gain.
My purpose is to achieve optical gain in an incoming CW Laser centered at 1550 nm and see the saturation behaviour of the SOA device.
Unfortunately until now i am achieving only the same output from the device, and it seems its output is the same even if i remove the CW laser.
Is there a simple way to configure the TWLM to achieve that? Or is there another component more suitable for an SOA?
I have done a sweep on the laser power, the following picture represents that
