Design And Implementation Of High-Performance Optical Interconnection Network Using MEMS Optical Switch

Optical switching has become one of the key techniques of optical network. MEMS-based all optical switch utilizes micro-electromechanical systems (MEMS) technology to provide strictly non-blocking photonic switching of fiber-optic traffic. All-optical approach eliminates the need for optical-to-electrical conversions, providing switching solutions that are independent of wavelength, data rate, and signal format. It has become the highly important application of optical communications. On the basis of the high-speed network interface card accomplished by our research group, a new structure for a giga-bit per second optical interconnection network has been designed using optical switch and full bandwidth peripheral component interconnect (PCI) interface cards. It can provide an interconnecting network with high bandwidth and low latency of communications for clusters system.
