摘要
我们在场在平面周期的波导的指南模式回声的分散关系，两个为极化 s (TE 模式) 并且极化 p (TM 模式) 事件飘动。为固定同类的平面波导， TE eigenmode 的分散曲线根本不能穿过 TM eigenmode 的。是说在某个波长， TE 和 TM 模式不能与一样的繁殖是激动的不变的。由于在平面周期的波导的布拉格思考， TE 漏的模式的分散曲线可以在第一个 Brillouin 地区与 TM 漏的模式的交叉。我们采用这些交叉完成极化无关的指南模式回声过滤器。[从作者抽象]
We present the dispersion relation of guided-mode resonances in planar periodic waveguides, both for s-polarized （TF, mode） and p-polarized （TM mode） incident waves. For a fixed homogeneous planar waveguide, dispersion curves of the TE eigenmode cannot cross that of the TM eigenmode at all. That is to say, at a certain wavelength, TE and TM modes cannot be excited with the same propagation constant. Due to Bragg reflection in the planar periodic waveguide, dispersion curves of the TE leaky mode may intersect with that of the TM leaky mode in the first Brillouin zone. We employ these intersections to achieve polarization-independent guided-mode resonance filters.
