摘要

本文通过引入两个60/spl度/的光滑弯曲，每个弯曲都有一个孔，研究了平面pcw中的弯曲。pcw是通过去掉单排孔来定义的。利用锥形脊波导获得了光到pcw的进出耦合。通过使用两个LED光源，在1330 nm和1550 nm的中心位置，用光谱分析仪记录了TE和TM偏振的透射光谱。三维时域有限差分模拟成功地解释了观察到的TE和TM极化的弯曲损耗。

Propagation of TE and TM polarised light through smoothed sixty degree bends in planar photonic crystal waveguides

In this paper, bends in planar PCWs are investigated by introducing two smoothed 60/spl deg/ bends each having one hole. The PCWs are defined by leaving out single rows of holes. In and out coupling of light to the PCWs is obtained utilising tapered ridge waveguides. Transmission spectra are recorded for both the TE and TM polarisation with an optical spectrum analyser by using two LED sources centred at 1330 nm and 1550 nm. The 3D FDTD simulations successfully explain the observed bend losses both for the TE and TM polarisations.
