We propose a new method for implementing a large optoelectronic (O-E) crossbar interconnect switch [1], Based on an emerging vertical-cavity surface-emitting laser (VCSEL) technology, a passive angle-multiplexed beam steering architecture is proposed as a key component of the O-E crossbar. Various optical system parameters are evaluated. Since there is no optical fan-out power loss, the interconnect capacity of the proposed system is determined by the diffraction-limited receiver power cut-off and therefore interconnection of more than 1,000 nodes with a per node bandwidth of 1 GHz using today's technology is possible.
