We fabricated a 2: 1 multiplexer IC (MUX) with a retiming function by using 1-µm self-aligned InP/InGaAs/InP double-heterojunction bipolar transistors (DHBTs) with emitter mesa passivation ledges. The MUX operated at 120Gbit/s with a power dissipation of 1.27W and output amplitude of 520mV when measured on the wafer. When assembled in a module using V-connectors, the MUX operated at 113Gbit/s with a 514-mV output amplitude and a power dissipation of 1.4W.
