100-Gbit/s logic IC using 0.1-/spl mu/m-gate-length InAlAs/InGaAs/InP HEMTs

High-speed electrical multiplexing and demultiplexing are keys in optical fiber communication systems. In the last few years, multiplexing operations at over 80 Gbit/s have been reported for selector ICs using InP HEMT and InP HBT technologies. The record operating speed is, however, still 90 Gbit/s, which was characterized only by means of a waveform observation on digitizing sampling oscilloscope. This paper describes 100-Gbit/s multiplexing and demultiplexing error-free logic operations in InP HEMT technology.
