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 nonoptimized hybrid version, the smart pixel exhibits opto-optical switching with a contrast of 35 dB, an optical gain of 55 dB and a 3 dB bandwidth of 90 MHz. T...

Zusammenfassung:We present a smart pixel with surface-normal optical input and output beams using a vertical cavity surface-emitting laser. In its present nonoptimized hybrid version, the smart pixel exhibits opto-optical switching with a contrast of 35 dB, an optical gain of 55 dB and a 3 dB bandwidth of 90 MHz. The optical switching energy is 715 fJ. NOR, and NAND logic operations at 4 Mbit/s with a fan-out of 5 are also demonstrated.
