Abstract

An all-optical fiber-optic crossbar switch capable of interconnecting N input fibers to M output fibers with an arbitrary interconnect pattern has been constructed. The switch can use any 1-D or 2-D spatial light modulator capable of realizing NxM pixels, and can be configured for permutations, full or partial broadcast, or "wired oring" of several inputs to a given output. Values of N and M achievable depend on the light efficiency of the switch components and the data rate. A 4x4 switch has been built; in a computer switching environment, the approach is capable of realizing a 16x16 switch at 1 Gb/s and a 32x32 switch at 100 Mb/s. The development of the switch has included construction of both a PLZT switch array and a magneto-optic switch array. We will report on the investigations of both technologies. Reconfiguration times in the range of a few microseconds to a few tens of microseconds are of interest.
