In two-dimensional optical chip applications, the optical wave is classified to two modes according to its polarization: TE and TM. It is desirable to integrate multiple optical wave control devices for different polarizations onto the same plane at the scale of the wavelength. Here we demonstrate a periodic two-pattern photonic crystal with a large, complete photonic bandgap (PBG). It comes from the superposition of two substructures: one contributes the TM PBG and the other contributes the TE PBG. By purposely introducing defects into the substructures, photonic devices for different polarizations can be integrated to bend, split, and resonate TM/TE waves simultaneously on the same plane.
在二维光学芯片应用中，根据其偏振方向，光被分为两种模式：TE 和 TM。理想情况下，希望将不同偏振的多个光波控制装置集成到同一平面上，其尺寸与波长相当。在这里，我们展示了一种具有大的完全光子带隙 (PBG) 的周期性双图案光子晶体。它由两个子结构的叠加组成：一个贡献 TM PBG，另一个贡献 TE PBG。通过有意地在子结构中引入缺陷，可以将不同偏振的光子器件集成到同一平面上，从而同时弯曲、分裂和共振 TM/TE 波。
