我们采用拓扑优化（TO）方法来提高空气桥型二维光子晶体板中波导弯曲的传输带宽。我们通过实验证实，通过使用 TO 可以抑制带边缘附近较长波长的弯曲损耗。优化的弯曲显示出良好的性能，可与直波导相媲美。 (c) 2007 年美国物理研究所。
We employed the topology optimization (TO) method to improve the transmission bandwidth of waveguide bends in air-bridge-type, two-dimensional photonic crystal slabs. We experimentally confirmed that bend loss at longer wavelengths in the vicinity of the band edge was suppressed by using TO. The optimized bends showed good performance, comparable to that of straight waveguides. (c) 2007 American Institute of Physics.
