摘要：

The properties of the propagating field in multimode photonic crystal waveguides(PCWs)exhibiting no photonic band gaps (PBGs) are investigated.The transmission spectrum shows that the input field can be guided with high efficiency,and resemble index-guided modes owing to the combination of total internal reflection (TIR) and distributed Bragg reflection (DBR).Self-imaging effect happens and the filling fraction determines the beating lengths.The rows of air holes decide DBR coming from the mirrors on both sides of the guiding region,which governs the transmission spectrum.It provides a new way to realize the components for both polarizations by combining PBG and TIR effects in PCWs.
