论文摘要
量子气实验的多功能性极大地受益于应用可变电位的能力。在这里,我们描述了一种方法,该方法允许通过使用热诱导的镜面微结构技术的光谐振器几何形状的空间选择性变形来制备微腔光子的潜在结构。我们研究了由染料填充的微腔中的二维光子气体的热化,该微腔由波长分离的定制表面结构镜组成。具体而言,我们描述了在耦合的双ridge结构中热光子空间重新分布的测量值,其中光子在空间分裂的基态以不同的泵送几何形状的函数中形成了玻色子 - 因子凝结物。
The versatility of quantum gas experiments greatly benefits from the ability to apply variable potentials. Here we describe a method which allows the preparation of potential structures for microcavity photons via spatially selective deformation of optical resonator geometries with a heat induced mirror surface microstructuring technique. We investigate the thermalization of a two-dimensional photon gas in a dye-filled microcavity composed of the custom surface-structured mirrors at wavelength-scale separation. Specifically, we describe measurements of the spatial redistribution of thermal photons in a coupled double-ridge structure, where photons form a Bose-Einstein condensate in a spatially split ground state, as a function of different pumping geometries.
