The properties of the propagating field in multimode photonic crystal waveguides (PCWs) exhibiting no photonic band gaps (PBGs) are investigated.

研究了光子晶体多模波导在非光子带隙区光场的传输特性。

For PCWs with different degrees of concaveness, the power reaches about 80% at different focusing points when the morphology of the concave surface is optimized.

通过对褶皱表面的形貌优化，我们得到了不同曲率半径的高质量光子晶体波导聚焦器件，聚焦能量达到80%以上。
