15 /spl mu/m solder bonding of GaAs/AlGaAs MQW devices to MOSIS 0.8 /spl mu/m CMOS for 1 Gb/s two-beam smart-pixel receiver/transmitter

Abstract

A two-beam optical repeater circuit operates to 1 Gb/s, consumes 10 mW, occupies about 1100 /spl mu/m/sup 2/, and is realized with a technology capable of providing thousands of optical inputs and outputs to foundry-grade VLSI silicon CMOS circuitry. The technology provides this capability by attaching GaAs/AlGaAs multiple-quantum-well (MQW) modulators and detectors to VLSI CMOS with flip-chip solder bonding. The main unique features are summarized.
