Harmonic generation limitations in gain-switched semiconductor lasers due to distributed microwave effects

A large-signal, time domain semiconductor laser model that incorporates propagation effects within the cavity and a microwave circuit simulator are used to investigate distributed microwave effects on gain-switching performance. It is shown that the position of the feed point to the top electrode can have a significant influence on the harmonic content of the generated pulses, which is an important consideration in microwave/millimeter-wave signal generation schemes.
