This paper demonstrated a multi-channel Wavelength-Division-Multiplexing (WDM) system using photonic crystal structures. The system consists of a waveguide that realized by a defect row of photonic crystal and high Q-value micro-cavities. Two-Dimension (2-D) Finite-Difference-Time-Domain (FDTD) method is performed for simulation in this paper. The results showed good ability to filter an incident pulse into six spectral channels with a FHWM of 1.4nm at center wavelength 1550nm output channel.
