A compact 1×4 wavelength demultiplexer is proposed based on the directional coupling of periodic dielectric waveguides for optical communication wavelengths. With appropriate optimization, the 1×4 wavelength demultiplexer can route 1130, 1310, 1490, and 1700 nm wavelengths to corresponding out ports with a transmittance of more than 95%. This provides a simple and compact demultiplexer that is expected to be applied to highly dense photonic integrated circuits.
