Paper Abstract

This paper presents the design of a receiver used in a self- aligning optical interconnect. We have made use of spatial redundancy to increase the misalignment tolerance of a system of four 1 Gb/s free-space optical links. The receiver for this system is a rapidly re-configurable array that accepts nine low-amplitude, high-speed photocurrents, selects one of them, and then outputs that signal as a digital differential positive emitter coupled logic signal. The selection of which channel to amplify is based on received power, and is performed off-chip. Preliminary results indicate that the receiver performs with a low bit error rate up to 750 Mb/s.
