Abstract

A sensitive, high speed optical detector is needed for use in optical communications as well as for laboratory experiments. Recent experiments (1) have shown the GaAs MESFET to be potentially useful as a fast optical detector. We call this device an OPFET. This report summarizes new experimental results which show that the OPFET is both fast and sensitive and which identify the detection mechanism in this structure as photoconductivity. Calculations show that this device should give performance which exceeds that of PIN photo-diodes and rivals avalanche photodiodes. In addition, the structure is easy to integrate for use in optical circuits.
OPFET:一种新型高速光学探测器
在光通信和实验室实验中都需要灵敏、高速的光探测器。最近的实验(1)表明,GaAs MESFET作为一种快速光学探测器具有潜在的用途。我们称这种器件为OPFET。本文总结了新的实验结果,表明OPFET具有快速和灵敏的特点,并确定了该结构的检测机制为光电导率。计算表明,该器件的性能应超过PIN光电二极管和竞争对手雪崩光电二极管。此外,该结构易于集成用于光学电路。
