论文摘要
晶体固体中自发布里鲁因散射的选择规则通常被视为固有的材料特性，将激发和信号的相对极化锁定在整体中。在这项工作中，我们通过在椭圆形微柱中的光谐振来独立地操纵这些极化状态，并在20-100 GHz范围内展示了基于极化的滤波方案，对电信应用很重要。使用椭圆形的微柱对选择规则的这种强烈修改可以扩展到任何具有局部极化敏感模式的光学系统，例如等离激元谐振器，光子晶体，双重光子晶体，双发性微型和纳米结构。因此，我们的极化控制协议将在光学机械，光电和量子光学设备中的光结合相互作用的工程中找到应用。
The selection rules governing spontaneous Brillouin scattering in crystalline solids are usually taken as intrinsic material properties, locking the relative polarization of excitation and signal in bulk. In this work, we independently manipulate these polarization states by means of optical resonances in elliptical micropillars and demonstrate a polarization-based filtering scheme for Brillouin spectroscopy in the 20-100 GHz range, important for telecom applications. This strong modification of selection rules using elliptical micropillars can be extended to any optical system with localized, polarization-sensitive modes, such as plasmonic resonators, photonic crystals, birefringent micro-, and nanostructures. Our polarization control protocol will thus find applications in the engineering of light-matter interactions in optomechanical, optoelectronic and quantum optics devices.
