Abstract

The main limitation to the practical utilization of transparent semiconductor optical amplifiers (SOA) in optical functional devices is the strong dependence of the transparency carrier density on the pump pulse power. Such power dependent SOA transparency would cause pattern-dependent switching. Results show that by increasing the linear waveguide losses from 0.6 dB to 4 dB and suitably adjusting the pulse photon energies, the variation of transparency carrier density can be decreased by a factor of 5 for a pump energies up to 12 pJ. It can also be decreased by a factor of 2 if the SOA length is increased from 125 μm to 500 μm.
