OPTICAL RECEIVERS FOR OPTOELECTRONIC VLSI

We describe Our work on the design and testing of optical receivers fo r use in optoelectronic VLSI, Tile focal nature of the optoelectronic VLSI system permits novel receiver designs, incorporating multiple opt ical beams and/or synchronous operation, while the requirement of real izing large numbers of cr a receivers on a single chip severely constr ains al ea and power consumption. We describe four different receiver designs, and their different operating modes. Results include 1-Gb/s h igh-impedance, two-beam diode-clamped PET-SEED receivers, single and d ual-beam transimpedance receivers realized with a hybrid attachment of multiple-quantum well devices to 0.8-mu m linewidth CMOS operating to 1 Gb/s, and synchronous sense-amplifier-based optical receivers with low (similar to 1 mW) power consumption. Finally, we introduce a measu re of receiver performance that includes area and power consumption.
