SMART PIXEL USING A VERTICAL-CAVITY SURFACE-EMITTING LASER

We present a smart pixel with surface-normal optical input and output beams using a vertical cavity surface-emitting laser. In its present n onoptimized hybrid version, the smart pixel exhibits opto-optical swit ching with a contrast of 35 dB, an optical gain of 55 dB and a 3 dB ba ndwidth of 90 MHz. The optical switching energy is 715 fJ. NOR, and NA ND logic operations at 4 Mbit/s with a fan-out of 5 are also demonstra ted. (C) 1997 American Institute of Physics. [S0003-6951(97)01650-1].
