We present an optical "enantio-selective switch" that, in two steps, turns a ("racemic") mixture of left-handed and right-handed chiral molecules into the enantiomerically pure state of interest. The optical switch is composed of an "enantio-discriminator" and an "enantio-converter" acting in tandem. The method is robust, insensitive to decay processes, and does not require molecular preorienta...

An optical switch structure which combines a planar lightwave circuit and liquid crystal is proposed and experimentally demonstrated. The switching is realized by inducing total internal reflection through controlling the refractive index of the liquid crystal. The principle and the design of the integrated optical switch are described. Experimental results suggest that anchoring of the liquid ...

SUMMARY State of the arts on guided-wave optical switch arrays are reviewed. In this paper, electro-optic Ti:LiNbO 3 devices are mainly described in comparison with crosspoint switch element structures and switch array architectures. Packaging technologies and stability problems are discussed for practical system applications. Recent development on other materials such as semiconductor waveguid...

A field trial of 4K uncompressed streaming over 80 (8λ x 10) Gbps colored optical packet switching network with SOA based broadcast-and-select switch and stacked optical-code (OC) label processing is reviewed. Introduction “4K” motion pictures (3840x2048 pixels), which is 4 times pixel counts of high-definition (HD), are promising imaging technology for digital cinema, computer visualization, a...

We demonstrate for the first time a field trial of 80 (10 x 8) Gbps colored optical packet switching of 4K and 2K uncompressed streaming using SOA based broadcast-and-select switch and optical-code label processing. Introduction “4K” motion pictures (3840x2160 pixels), 4 times pixel counts of high-definition (HD), are promising imaging technology for digital cinema, computer visualization, and...

This paper discusses the influence of setup message processing time and optical switch configuration time on the performance of IP over optical burst switched mesh networks using one-way resource reservation protocols. It is shown that the network performance is almost independent of the optical switch configuration time for values smaller than 0.1ms. It is shown that setup message processing t...

This paper proposes new switch architectures for hierarchical optical path cross-connect (HOXC) systems. The architectures allow incremental expansion of system scale in terms of the number of input/output fiber ports, wavebands, and optical paths per waveband. These features assure the cost-effective introduction of HOXCs even at the outset when traffic volume is not so large. Furthermore the ...

In this paper two different paradigms to realize a scalable all-optical packet switch with label swapping will be presented. All the functions required for switching the packets are based on all-optical signal processing without any electronic control. This allows very low latency and potential photonic integration of the systems. We report for both techniques experimental results showing the r...
