Abstract :
We presented and discussed experimental and numerical results on the effective alpha factor in bulk SOAs. We showed that the magnitude of alpha factor increases by increasing the dc bias current. Moreover we demonstrated that the effective alpha factor significantly increases with the length of the active region, because of the nonlinear gain compression. This characteristic can be very important for applications based on cross phase modulation in SOAs
