چکیده
Over the last few years an amazing amount of interest has emerged for applications of micro electro-mechanical systems (MEMS) in telecommunications. Silicon-based optical MEMS have proven to be the technology of choice for lowcost scalable photonic applications because they allow mass manufacturing of highly accurate miniaturized parts, and use materials with excellent mechanical and electrical properties. Applications include tunable lasers, optical switches, and tunable filters. The use of MEMS for optical switching has turned out to be most attractive since this application could revolutionize fiber optic telecommunications. In this article we discuss the technology, performance, and reliability of 2D MEMS optical switches. We show that this technology meets the scalability, performance, and reliability requirements for important applications in fiber optic networks.

متن کاملEnhanced designs on MEMS L-switching matrix
Micro-Electro-Mechanical System (MEMS) is one of the few commercial platforms for building optical switches. 2D MEMS L-switching matrix has been introduced recently to double the sizes of 2D MEMS crossbar switches. The sizes of switches are mainly limited by the Gaussian signal loss associated path difference. Though the design of L-switching matrix improves system scalability but it suffers in...
