A novel all-optical-path-routing technique is described, which employs four-wave mixing in a dispersion-shifted fiber and a wavelength router with fiber gratings and optical circulators. The signal wavelength is converted to a specified channel by four-wave mixing, and is finally selected with the wavelength router. It offers good potential for enabling the number of output ports of a wavelength router to be extended as it provides a very sharp spectral edge and a low insertion loss.
