40 Gbit/s monolithic digital OEIC composed of unitravelling-carrierphotodiode and InP HEMTs

Abstract
An optoelectronic integral circuit (OEIC) receiver with a measured sensitivity of –27.5 dBm for a 40 Gbit/s return-to-zero optical signal is described. The results indicate the potential of current in high-speed optical communication systems.
