The authors report ultra-high-speed digital IC modules that use 0.1-μm InAlAs / InGaAs / InP HEMTs for broadband optical fiber communication systems. The multiplexer IC module operated at up to 70 Gbit / s, and error-free operation of the decision IC module was confirmed at 50 Gbit / s. The speed of each module is the fastest yet reported for its kind.
