摘要：

We have proposed and fabricated a photonic parallel memory (PPM) which is an array of 32 x 32 optoelectronic bistable switches. The switch consists of a heterojunction phototransistor (HPT) and a light-emitting diode (LED), and optical positive feedback from LED to HPT is the cause of bistability. PPM can be written in and read out with 1-kb parallel optical signals. PPM has been fabricated successfully and memory operation has been demonstrated as expected. Dissipation current for a single switch and the input optical power necessary to turn on the switch were 600 μA and 20 μW, respectively. Light pulse with a width of 5 ns was able to turn on the switch and product of turn-on power and pulsewidth for short pulse region was 1.5 pJ. © 1990 IEEE
