In this paper we review the progress made in implementing nonlinear directional couplers as potential all-optical switching devices. We will discuss the operation of the coupler and its application as an all-optical multiplexing, demultiplexing element and consider the possibility of integrating more than one nonlinear switching element. The limitation of dispersion and nonlinear absorption will also be addressed.

A pump-induced refractive index change was measured in a passive GaInAsP waveguide together with its temporal response. Also, the temporal response of distributed feedback (DFB) waveguide transmittance modulated by the pump-induced index change was experimentally investigated for an application to all-optical switching devices.
