Abstract

Recently a very promising active bistable vertical-to-surface transition electrophotonic device was developed to perform chip-to-chip optical interconnects—the PnpN photothyristors (Fig. 1). When used in the configuration of a differential pair, these multilayer III-V semiconductor (GaAs/AlGaAs) structures are capable of emitting a binary optical signal, when receiving a 250 fj optical input and controlled by a voltage cycle with period less than 70 ns.¹
