Ths paper reviews benefits for the integration of optical components into Photonic Light Circuits (PLC's), with a particular emphasis on the integration of optical switching elements. The requirements for the optical switches in these circuits will be discussed and the suitability of various switching technologies for meeting these requirements will be considered.
