A no¨el filter structure is presented in this paper to reduce the crosstalk in cross connection and switching in all-optical networks ( ) based on dense wa¨elength-di¨ision multiplexing DWDM . Following the principle of an optical film filter, the filter is constructed by a dielectric wa¨eguide with
