Abstract
The optical thyristor differential pair is a promising device for digital optical information processing. This bi- stable optoelectronic switch is usually implemented as a double-heterojunction PnpN structure in the GaAs/AlAs material system. In the off-state, it has a high impedance, while in the on-state, it is conductive and emits light perpendicularly to the surface with the emission characteristics of a LED. Recently experiments have been conducted by a joint research team of the Vrije Universiteit Brussel and the Interuniversity Micro- Electronics Centre (IMEC) to transmit information between adjacent pairs of thyristors on the same wafer, demonstrating cascadability. Transcription rates of 50 MHz at 7.2 fJoules optical input energy for an optical window area of 20 x 30 lim2 have been obtained [1]. The latest designs allow operation of the thyristor pairs at 3.3 V levels which makes it possible to integrate these devices with silicon VLSI circuits and to consider the development of smart pixel type elements with enhanced functionality.
