Novel Optically Bistable Optoelectronic Device for Infrared Signal Processing

Not Accessible

Your library or personal account may give you access


We report a new optically bistable opto-electronic (OBOE) InSb device which, while retaining all-optical switching capability can also be switched (ON and OFF) electrically. A photo-conductive monitoring system is utilised to give readout of the logic state. Applications of OBOE arrays for image processing are discussed. The latest performance data for the switch time (150 ns) and switching power (500 μW) of fully optimised InSb bistable devices are reported.
