A linear waveguide in an annular photonic crystal composed of a square array of annular dielectric rods in air is demonstrated to guide transverse electric and transverse magnetic modes simultaneously. Overlapping of the guided bands in the full band gap of the photonic crystal is shown to be achieved through an appropriate set of geometric parameters. Results of Finite-Difference Time-Domain simulations to demonstrate polarization-independent waveguiding with low loss and wavelength-order confinement are presented. Transmission through a 90 degrees bend is also demonstrated.
在由空气中方形排列的环形介质棒组成的环形光子晶体中的线性波导被证明能够同时引导横电模和横磁模。通过一组适当的几何参数，实现了光子晶体全带隙中导带的重叠。给出了有限时域差分模拟的结果，以证明具有低损耗和波长级限制的偏振无关波导。还展示了通过90度弯曲的传输。
