摘要：
We demonstrate highly efficient transmission of light around sharp corners in photonic bandgap waveguides. :Numerical simulations reveal complete transmission at certain frequencies, and very high transmission (>95%) over wide frequency ranges. High transmission is observed even for 90 degrees bends with zero radius of curvature, with a maximum transmission of 98% as opposed to 30% for analogous conventional dielectric waveguides. We propose a simple one-dimensional scattering theory model with a dynamic frequency-dependent well depth to describe the transmission properties.
