摘要

The switching operation is one of the crucial functions of all information processing or information transmission systems. Some of them, like a communication network or a computer, are generally composed of connected switches. The vital simplification for optical systems would be a possibility to avoid multiple conversions of information from a photonic to an electronic form to provide switching at subsequent nodes of the net. All-optical switching devices can give this chance. Generally an all-optical switching operation occurs when output characteristics of the device can be determined either by the parameters of the input signal or by a separate control beam. A number of devices to switch optical signals have been proposed. The switch ng operation in the first group of them relies on optically controlled power exchange between two modes guided in an integrated optics or fibre system. Functioning of the second group relies on optically induced changes in phase difference between two pulses.
