Engineering Room-Temperature Exciton-Polgritonics

随着社会对技术的依赖增加，对快速和安全的信息传输和日益复杂的计算能力的需求继续增长。为了开发多功能系统来满足这些迫切的需求，研究人员正在致力于创造节能的紧凑型光子和光电子器件，这些器件由材料和纳米结构中的新物理过程控制。通过拟议的计划，我们将把激子-极化电子器件设计成一个可扩展的固态光子平台。激子-极化激子具有双重的光-物质性质，这是由于它们的腔光子和量子井激子的强耦合造成的。物质部分赋予粒子-粒子相互作用产生的强非线性和自发相干性，而波动部分赋予极轻质量产生的超快传播。这些特性使我们能够构建超低功率光源和光学逻辑器件，与传统器件相比，预计功率增益将达到10-100倍。固有的平面结构支持集成其他组件以实现可伸缩性。

The demand for the rapid and secure transfer of information and for increasingly complex computational power continues to grow as society’s reliance on technology increases. To develop multi-functional systems to meet these pressing demands, researchers are pursuing the creation of energy-efficient compact photonic and optoelectronic devices governed by novel physical processes in materials and nanostructures. Through the proposed program, we will engineer exciton-polaritonic devices as a scalable solid-state photonic platform. Exciton-polaritons have a dual light-matter nature, resulting from their strongly coupled cavity photons and quantum-well excitons. The matter portion bestows strong nonlinearity and spontaneous coherence arising from particle-particle interactions, and the wave portion bestows ultrafast propagation arising from its extremely light mass. These properties enable us to build ultralow power light sources and optical logic devices, with a predicted 10-100 fold power gain compared to traditional devices. The innate planar structure supports integration of other components for scalability.
