Optical demultiplexer using coupling between nonidentical waveguides.
A demultiplexer using wavelength dependent coupling between nonidentical waveguides is proposed and demonstrated for single-mode fiber transmission systems. The demultiplexer, consisting of rf-sputtered glass thin film layers, demultiplexes 4880-A, 5145-A, and 6328-A light waves with larger than 14-dB crosstalk attenuations and with less than 5.2-dB insertion losses.
