Abstract:

In this work, we show a pulsewidth dependent self-phase modulation SPM of optical pulses in semiconductor traveling wave amplifiers due to nonlinear gain depletion and hot carrier thermalization, termed as the dynamic carrier cooling effect. The dynamic carrier cooling effect can be observed as a fast - 1 psec partial recovery of the gain of a semiconductor traveling wave amplifier when a femtosecond optical pulse propagates through the device. While SPM due to gain depletion has been observed before, this is the first observed of SPM due to the dynamic carrier cooling effect.
