ABSTRACT:
Optical signals are dispersed according to their wavelength by an optical path length difference generator that couples a single pathway conveying a plurality of different wavelength signals to multiple pathways separately conveying the different wavelength signals. The optical path length generator can be formed by a reflective stack having a plurality of partially reflective surfaces for reflecting successive portions of the energy of each of the different wavelength signals along different length optical paths.
