ABSTRACT:
A 2.times.2 optical switching element is described. Illustratively, the switching element includes first and second inputs for receiving optical radiation and first and second outputs for transmitting optical radiation. The switching element also includes mode conversion means for selectively switching optical radiation of a specific wavelength arriving via one of the inputs to either or both ouptus by selectively controlling the conversion of the radiation at the specific wavelength from one mode to another. An N.times.N switch may be formed from an array of the 2.times.2 switching element.
