    Abstract: In this paper, we have investigated photonic crystal based optical waveguides implemented into wavelength division
    multiplexing systems. The wavelength division multiplexing splitters based on a photonic crystal waveguide coupler with
    square lattice and triangle lattice are proposed. The wavelength multiplexing properties are numerically investigated by using
    the finite-difference time-domain method. The coupling length can be reduced by using triangle lattice in the photonic crystal
    waveguide coupler. The symmetrical splitter has two identical photonic crystal waveguide couplers and three output
    channels that splits a lightwave equally and transfers power to the opposite guide. The asymmetrical splitter has two different
    photonic crystal waveguide couplers and three output channels that output different wavelengths to the three output
    channels. Compared with traditional optical coupler, the sizes of PC coupler are expected to be drastically reduced from a
    few hundreds of micrometers to a few tens of micrometers. The PC couplers and splitters should enable novel utilizations for
    designing compact devices in photonic circuits.
