本文对晶格变形二维单线缺陷（W1）光子晶体波导弯曲的不同拓扑结构及其对弯曲传输性能优化的影响进行了扩展研究。通过优化设计，在5.2%的相对带宽下，透射率大于95%，光谱响应提高了6倍。实验结果表明，在III-V型半导体外延结构中实现的器件的传输效率为95%。
We present an extended study of different topologies for lattice-deformed two-dimensional single line-defect (W1) photonic crystal channel waveguide bends and their effect on the optimization of the bend transmission properties. An enhancement of the spectral response by a factor of six was obtained, with the optimal design providing transmission greater than 95% over a 5.2% relative bandwidth. Experimental results for devices realized in III–V semiconductor epitaxial structure show a transmission efficiency of 95%.
