Abstract :
Chip gain of 26 dB upon amplification of 1.3 picosecond pulses at frequencies up to 80 GHz is demonstrated for temperature stable QD-SOAs. Pulse broadening in the below 200 fs range is observed. The results agree with our predictions on decoupling of gain and index of refraction in Q-based amplifiers. Modelling of wavefunctions in stacked QD-layers based on 8-band k.p-theory indicates the potential of obtaining in the future polarisation insensitive amplification
