Total-reflection wavelength demultiplexer using a highly dispersive medium.
We propose a new type of optical wavelength demultiplexer that employs the wavelength dependence of reflectivity at the interface plane for two media having different dispersive characteristics. This device utilizes a total-reflection phenomenon and guarantees a perfectly zero cross talk or less than 4 x 10(-4) cross talk, respectively, at any wavelength shorter or longer than the design-window-wavelength region.
