Abstract

Wavelength dispersion in an optical demultiplexer (10) is accomplished by varying propagation constants of a central pathway (16) traverse to the direction of wavefront propagation through the central pathway (16). The propagation constant can be varied by changing the dimensions or refractive qualities of the central pathway, which can be formed as a common waveguide (36) or as plurality of individual waveguides (16).
