Abstract:
A configuration for multiplexing and/or demultiplexing signals of a plurality of optical data channels of different wavelength, the configuration comprising:a waveguide for transmitting the signals; a plurality of wavelength-selective mirrors; and a planar substrate having a planar surface and an edge and being formed with a plurality of cutouts each extending at a defined angle, said defined angle being different than 90Â° with respect to said planar surface; said waveguide disposed in said substrate, said plurality of said cutouts interrupting said waveguide at successive points; a respective one of said plurality of said wavelength-selective mirrors disposed in each one of said plurality of said cutouts causing mirror light to be coupled obliquely to said planar surface of said substrate and to pass through said planar surface.
