Abstract: We designed two types of optical splitter with 4 channels and 6 channels, respectively, by introducing column defects with different sizes at different positions of the photonic crystal. The variation of defects would change the transmission. Using finite-difference time-domain method for simulation, we obtained the splitter with transmittance in a certain proportion. The results show that the column defects in photonic crystal waveguide can control the transmission. The light was transferred in the optical splitter in proportion into four and six ports. The results have the important theoretical significance for the design of the optical integrated circuits.
