论文摘要
集成的电流开关是现代光电学发展的基本要素之一。作为光子系统的架构，具有源自激子和光子的独特特性的混合骨化准颗粒的激子偏振子已显示出很大的希望。对于该系统，我们通过将电场应用于充满有机微生物的微腔，证明了发射强度和冷凝阈值的显着改善。我们的理论研究表明，电场使激子偶极性并诱导激子 - 果胶相互作用和北极星寿命的增强。基于这些电场引起的变化，在室温下实现了次纳秒电场增强的偏振层冷凝水开关，为在强烈的轻度耦合方向上开发芯片上积分的光子设备提供了基础。
Integrated electro-optical switches are essential as one of the fundamental elements in the development of modern optoelectronics. As an architecture for photonic systems, exciton polaritons, that are hybrid bosonic quasiparticles that possess unique properties derived from both excitons and photons, have shown much promise. For this system, we demonstrate a significant improvement of emitted intensity and condensation threshold by applying an electric field to a microcavity filled with an organic microbelt. Our theoretical investigations indicate that the electric field makes the excitons dipolar and induces an enhancement of the exciton-polariton interaction and of the polariton lifetime. Based on these electric field induced changes, a sub-nanosecond electrical-field-enhanced polariton condensate switch is realized at room temperature, providing the basis for developing an on-chip integrated photonic device in the strong light-matter coupling regime.
