We have investigated the photonic modes at the surface of three-dimensional photonic crystals fabricated using a top-down approach involving two-step etching at angles of ± 45°. Numerical simulations revealed the properties of these surface modes, including their polarization characteristics and dependence on the surface structure. The formation of surface modes was experimentally demonstrated using an evanescent-coupling method and agreed well with the simulations.
我们研究了采用自上而下方法制造的三维光子晶体表面的光子模式，该方法涉及以±45°角进行两步蚀刻。数值模拟揭示了这些表面模式的特性，包括它们的偏振特性以及对表面结构的依赖性。使用倏逝耦合方法通过实验证明了表面模式的形成，并且与模拟结果吻合良好。
