Abstract
Wavelength dispersion in an optical demultiplexer is accomplished by varying propagation constants of a central pathway traverse to the direction of wavefront propagation through the central pathway. 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 or as a plurality of individual waveguides.
