Based on the coupling between photonic crystals(PCs) waveguide and micro-cavity,a new method to design wavelength division multiplexing(WDM) is proposed.By changing the position of border dielectric rods of micro-cavity and adopting the output waveguide with a 60o bend,the property of micro-cavity is optimized.The new WDM is designed based on the model.And by modulating the border dielectric rods,different wavelengths can be coupled into the micro-cavity,and then are output from the load waveguide selectively.Only by adding a reflective layer in the bus waveguide,the transmission efficiency of output wavelengths is greatly improved.
