摘要：
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 60° 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. © 2010 Tianjin University of Technology and Springer-Verlag Berlin Heidelberg.
