A detailed traffic analysis of optical packet switch design is performed. Special consideration is given to the complexity of the optical buffering and the overall switch block structure is considered in general. Wavelength converters are shown to improve the traffic performance of the switch blocks for both random and bursty traffic. Furthermore, the traffic performance of switch blocks with a...

A performance analysis of an optically interconnected packet-scheduling switch network is presented. The scheduling switch uses a branch of feed-forward delays for each input port, interconnected with elementary optical switches to resolve contention. The scheduling switch is guaranteed to be lossless under a certain smoothness property condition. We investigate the packet-loss performance of t...

We present a device design and fabrication of a novel hollow-waveguide optical switch consisting of a directional coupler with variable air cores. The numerical simulation and experimental characterization of the proposed optical switch performance is discussed. Switching operation is achieved by mode-field change and coupling beat length in the directional coupler section, as the air core thic...
