Optoelectronic 12 demultiplexing based on resonant tunnelling diodes and pin-photodetectors

A concept for 2:1 demulliplexing of an optical data stream has been developed and verified by transient simulation. The monolithic integration of broadband pin-photodiodes and resonant tunnelling diodes on InP-substrate allow the realisation of a demultiplexer circuit based on the principle of monostable-bistable logic elements (MOBILE) with very low complexity and device count. A design of two MOBILE gates is introduced and verified by simulation.
