Engineering Room-Temperature Exciton-Polgritonics

随着社会对技术的依赖不断增加，对信息快速安全传输和日益复杂的计算能力的需求也在不断增长。为了开发多功能系统来满足这些迫切的需求，研究人员正在追求由材料和纳米结构的新物理过程控制的节能紧凑型光子和光电子器件的创造。通过提出的计划，我们将设计激子偏振器件作为可扩展的固态光子平台。激子-极化子具有双重光-物质性质，这是由它们的强耦合腔光子和量子阱激子造成的。物质部分具有由粒子-粒子相互作用产生的强非线性和自发相干性，而波部分由于其极轻的质量而具有超快传播。这些特性使我们能够构建超低功耗光源和光逻辑器件，与传统器件相比，预计功率增益为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.
