Abstract :
We report on all-optical switching characteristics of a novel low temperature grown asymmetric Fabry-Perot (AFP) InGaAs-InAlAs MQW saturable absorber device, in which improvement of performance with respect to conventional AFP all-optical switches is provided by coupled and short cavity configurations. SubpJ pump pulse (-800 fJ) operation is realized with fairly high contrast ratio (-10 dB) over a broad bandwidth (-7 nm)
