ABSTRACT:
The efficiency of an N.times.N waveguide grating router may be increased in many applications by incorporating at least one output waveguide, such as an (N+1).sup.st waveguide, positioned for capturing second order diffraction optical energy from a free-space region in the router. The second order diffraction optical energy is delivered at a wavelength or at wavelengths corresponding to that wavelength or those wavelengths output on a particular associated one of the original N waveguide outputs for the router.
