ABSTRACT:
An out-of-phase self-imaging waveguide integrated optical wavelength demuplexer having an input waveguide containing light of two different wavelengths. The demultiplexer has a 1-by-2 self-imaging power splitter, a first intermediate waveguide containing the two wavelengths of light, a second intermediate waveguide longer than the first intermediate waveguide, a 2-by-2 self-imaging coupler having the first and second intermediate waveguides as inputs, an output waveguide containing light of one wavelength only, and an output waveguide containing light of the other wavelength only.
