High-speed resonant-cavity-enhanced Schottky photodiodes

Summary form only given. The bandwidth capabilities of optical-fiber telecommunication systems are still not fulfilled with present performances of optoelectronic devices. Schottky photodiode, with 3-dB operating bandwidth exceeding 200 GHz, is one of the best candidates for high-speed photodetection. However, like p-i-n photodiode, Schottky photodiode also suffers from bandwidth-efficiency trade-off. A recent family of resonant-cavity-enhanced (RCE) photodetectors has the potential to overcome this trade-off. In this paper, we report our work on design, fabrication, and testing of high-speed RCE Schottky photodiodes.
