Monolithic integration of pin/HBT optical receiver with HBT comparator on InP substrate

In summary, a pin photodiode, a transimpedance-type preamplifier, and a comparator have been monolithically integrated on an InP substrate with pin/HBT integration technology. The receiver OEIC with a comparator showed a sensitivity of -36.0 dBm at a bit error rate of 1/spl times/10/sup -9/ for 125 Mb/s optical signals. The successful integration of digital circuits with analog circuits and optical components promises a realization of high-performance parallel optical interconnections in the near future.
