4/spl times/4 ATM crossbar using N/sup 4/ global FSOI

The integration of optoelectronic devices with conventional electronics will ultimately enable free space optical interconnects (FSOI) for high speed switching applications. Specifically, the development of smart pixels allows compact integration of optics and electronics for use in various systems and applications. OptiComp has integrated these smart pixel arrays into a high performance optoelectronic computing (HPOC) module which is composed of an array of 850 nm VCSELs, laser drivers, diffractive optical interconnect elements (DOIEs), detectors, and receivers. The HPOC module was used to implement a 4 /spl times/ 4 crossbar switch for ATM by exploiting global (N/sup 4/) FSOI.
