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.

随着社会对技术依赖的增加，对快速和安全的信息传输以及对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以满足这些迫切的需求，研究人员正在寻求创建由材料和纳米结构中的新物理过程控制的节能紧凑型光子和光电器件。通过拟议的计划，我们将工程激子极化激元器件作为一个可扩展的固态光子平台。激子-极化激元具有光-物质双重性质，这是由它们的强耦合腔光子和量子阱激子引起的。物质部分赋予强烈的非线性和自发相干性，这是由粒子-粒子相互作用引起的，而波部分赋予超快传播，这是由其极轻的质量引起的。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，预计功率增益为10-100倍。固有的平面结构支持其他组件的集成，以实现可扩展性。
