The basic optical switch in optical interconnection networks is a 2times2 optical switch which provides two switching states: the "straight" state and the "swap" state. Several kinds of optical switch have been presented such as polarization selective elements combined with electro-optic halfwave plates. Using these basic optical switches to construct a(More)
The double-layer networks have the advantages of being strictly nonblocking and having a simpler routing algorithm, the lowest system insertion loss, a zero differential loss, fewer drivers, fewer interconnection lines, fewer crossovers, and the best signal-to-noise-ratio characteristic compared with any nondilated network. Using holographic optical(More)
A nonblocking 4 times 4 optical switch with polarization selective elements has been proposed, which control configuration has been changed. Compared with other nonblocking 4 times 4 optical interconnection network with polarization selective elements, this switch has lower insertion loss and requires fewer elements. In this presentation, this nonblocking 4(More)
Multicast communications have become more and more important recently, especially in their applications in multimedia communication, quality of service (QoS), video conferencing, and distance education. In a point-to-point (PTP) optical communication system, how to provide multicast services is an essential issue. There are some advantages of active(More)
