摘要
A low loss photonic crystal （PhC） waveguide having rectangular air holes in Si core is proposed having an average group index of 55 in the bandwidth of 1.2 THz. The possible propagation losses due to inefficient coupling arc also investigated for proposed structure. It is found that high transmission is obtained for a broad bandwidth from the output of the finally designed heterogeneous waveguide consisting of a slow liquid crystal infiltrated PhC waveguide surrounded by fast PhC waveguides on both sides.
