Fabrication of a 4 · 4 strictly nonblocking SOI switch matrix
نویسندگان
چکیده
A 4 · 4 strictly nonblocking thermo-optical switch matrix based on Mach–Zehnder (MZ) switching unit was designed and fabricated in silicon-on-insulator (SOI) wafer. The paired multi-mode interferometers (MMI) were used as power splitters and combiners in MZ structures. The device presents an average insertion loss of 17 dB and an average crosstalk of 16.5 dB. The power consumption needed for operation is reduced to 0.288 W by adding isolating trenches. The switching time of the device is about 15 ls, which is much faster than that of silica-based switches. 2005 Elsevier B.V. All rights reserved. PACS: 42.82.Ds; 4282.Et; 42.82. m

A strictly nonblocking network based on nonblocking 4×4 optical switches
Recently, the demand for communication has been growing rapidly. Hence, optical multistage network technologies are more appreciated nowadays. A double-layer network is a strictly nonblocking network, and it has the lowest system insertion loss of nondilated networks. A Beneš network is a rearrangeably nonblocking network, and it has the same system insertion loss as a double-layer network. We ...
متن کاملExtended generalized shuffle networks: Sufficient conditions for strictly nonblocking operation
Since Clos gave the first construction of a strictly nonblocking multistage interconnection network, only a few other constructions have been proposed in almost a half-century. In this paper, we introduce a constructive class of networks which utilizes crossbars of virtually any size and for which the sizes can vary from stage to stage. The interconnection between stages is a generalized shuffl...
متن کاملVirtual Nonblocking Switching Networks
Nonblocking networks are always favored to be used as switching networks whenever possible. There are three types of nonblocking networks, namely rearrangeable nonblocking networks, wide-sense nonblocking networks, and strictly nonblocking networks. Large-scale wide-sense nonblocking networks and strictly nonblocking networks may be infeasible due to their high cost. In contrast, rearrangeable ...

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...
