论文摘要
有效的光学经典和量子信息处理对轻型新颖要求施加：阈值低的手性。在这项工作中，我们证明了由于新兴的光子Rashba-dresselhaus旋转轨道耦合（SOC）引起的光学模式的手性激光。为此，我们开发了一种基于富含双折射液晶（LC）和钙钛矿晶体的光腔的新电气调谐装置。我们在聚合物模板中cspbbr $ _3 $无机钙钛矿的单晶生长的新方法使我们能够在钙钛矿激子和腔体模式之间达到强烈的光耦合方案，并诱导北极星凝聚力。 LC对外部电场的敏感性使我们能够原位调整冷凝水能量并诱导合成SOC。这形成了一个线性极化或两个圆形极化分离的单个线性分离的冷凝物，发出相干的光。两个SOC制度之间的冷凝阈值的差异可用于用电压打开和关闭手性冷凝水发射。
Efficient optical classical and quantum information processing imposes on light novel requirements: chirality with low threshold non-linearities. In this work we demonstrate a chiral lasing from an optical modes due to emerging photonic Rashba-Dresselhaus spin-orbit coupling (SOC). For this purpose we developed a new electrically tunable device based on an optical cavity filled with birefringent liquid crystal (LC) and perovskite crystals. Our novel method for the growth of single crystals of CsPbBr$_3$ inorganic perovskite in polymer templates allows us to reach a strong light-matter coupling regime between perovskite excitons and cavity modes, and induce polariton condensation. The sensitivity of the LC to external electric fields lets us to tune the condensate energy in situ and induce synthetic SOC. This shapes the condensate between a single linearly polarized or two circularly polarized separated in momentum, emitting coherent light. The difference in the condensation thresholds between the two SOC regimes can be used to switch on and off the chiral condensate emission with a voltage.
