Forty-Gbit/s-class light communications integrated circuits (ICs) have been developed using the InP-based high electron mobility transistors (HEMTs) and have successfully demonstrated as a benchmark for future large-capacity networks. In this paper, a basic 40-Gbit/s optical sender/receiver configuration and typical operating waveforms of HEMT IC modules is presented. Novel high-speed digital circuit designs such as a super-dynamic flip-flop and ultra-broadband analog circuit design of distributed baseband amplifier were incorporated. The fabricated IC chips offer practical speed performance beyond 40 Gbit/s with good yield.
