The different types of optical switching
devices can operate on many different principles and can perform many different functions;
the author gives a qualitative overview of this field. Some of the concepts in the field
are explained both in the physical principles and types of devices and in the requirements
that systems impose on devices. The importance of considering devices in the context of
systems is emphasized. The author discusses nonlinear optical processes in general,
reviews some physical attributes of devices, and summarizes some systems requirements on
