The Implementation and Control of CMOS/SEED Optoelectronic Integrated Crossbar Interconnection Network

An optical implementation and its cont rol of optoelectronic integrated crossbar interconnection network is reported in t his paper.The CMOS／SEED smart pixel arrays with O／E light windows are used a s logical controlling switch nodes.High／lower modulating ratio of the output li ght density is about 1.4.The light beam is supplied by a 850 nm semiconductor la ser diode.8×2 spot arrays formed by a phase computed-generated grating are use d as the pump light beams for CMOS／SEED light modulators.High-precision 2-D op tical fiber bundle arrays are used as the I／O access devices.The control signal s are generated by computer parallel port.The corresponding software is develop e d.16×16 optical crossbar interconnection network is realized using our experime ntal setup.
