Ultra-low-power, long-wavelength photoreceivers for massively-parllel optical data links

PDF Version Also Available for Download.

Description

An ultra-low-power, long-wavelength photoreceiver based on InGaAs/InP heterojunction bipolar transistors is reported. The photoreceivers were designed for massively parallel applications where low-power density is necessary for both electrical and thermal reasons. We demonstrate two-dimensional, four-by-four arrays of photoreceivers for free-space optical data links that interface directly with 3.3 V CMOS ASICs and dissipate less than 12 mW/channel; lower power is possible. Propagation delays of {approx}1 nsec were measured and large signal operation of 800 Mbits/sec is demonstrated. The array is on a 500 {mu}m pitch and can be easily scaled to much higher density. The photoreceivers can be utilized in ... continued below
