Abstract

A novel operating technique has been developed for a differential optical switch based on a set of parallel-connected pnpn structures. The differential function at O.2nW input power and 400fJ input energy was realized with A1GaAs/GaAs pnpn devices. Its application to an optical S-R flip-flop was also demonstrated by introducing a storage operation of pnpn structures.
