论文摘要
我们研究了一个由两个具有Rashba-Dresselhaus自旋轨道耦合，TE-TM分裂和线性极化分裂的光子型腔组成的光子设备，该型号在光子分散剂的可糖化点上打开了可调的能量隙。产生积极寻址的本地浆果曲率。所提出的结构源于液晶腔中人造光子量规场设计的最新进步[K. Rechcińska等人，Science 366，727（2019）]。我们的研究为拓扑光子学，室温旋转旋转和对极端环境中光子带的量子几何结构提供了新的观点。
We investigate a photonic device consisting of two coupled optical cavities possessing Rashba-Dresselhaus spin-orbit coupling, TE-TM splitting, and linear polarisation splitting that opens a tuneable energy gap at the diabolic points of the photon dispersion; giving rise to an actively addressable local Berry curvature. The proposed architecture stems from recent advancements in the design of artificial photonic gauge fields in liquid crystal cavities [K. Rechcińska et al., Science 366, 727 (2019)]. Our study opens new perspectives for topological photonics, room-temperature spinoptronics, and studies on the quantum geometrical structure of photonic bands in extreme settings.
