A monolithically integrated logic photoreceiver with double-heterojunction bipolar transistors

摘要

A simplified logic photoreceiver with a photodetector directly connected to a decision circuit has been monolithically integrated with double-heterojunction bipolar transistors. Neither a preamplifier nor compensation circuits was used in this photoreceiver. A power estimation model was introduced to the simplified photoreceiver. Important device characteristics for error-free operation under practical conditions were quantitatively discussed. A 10-Gbit/s error free operation for a 1.55-/spl mu/m wavelength was successfully achieved.
