论文摘要
通过增加光学谐振器中存储的能量来增强光结合相互作用的能力本质上取决于它们与入射波前的耦合。在实践中，较弱的耦合可能是由于谐振器的不规则形状和/或周围散射环境中波浪的争夺所致。在这里，我们提出了一种非侵入性波前塑形技术，可为谐振器提供最佳的耦合。入射波前的相干控制依赖于有效刺激谐振器的波的延迟时间的延长。我们通过注入原位最佳波前在微波实验中展示了我们的概念，从而最大化存储在多个高渗透性介电散射器中的能量和嵌入在复杂环境中的扩展泄漏腔。我们希望我们的框架在增强光子材料中的光 - 物质相互作用以及增强能量收集时找到重要的应用。
The ability to enhance light-matter interactions by increasing the energy stored in optical resonators is inherently dependent on their coupling to the incident wavefront. In practice, weak coupling may result from resonators' irregular shapes and/or the scrambling of waves in the surrounding scattering environment. Here, we present a non-invasive wavefront shaping technique providing optimal coupling to resonators. The coherent control of the incident wavefront relies on the lengthening of delay times of waves efficiently exciting the resonator. We demonstrate our concept in microwave experiments by injecting in-situ optimal wavefronts that maximize the energy stored in multiple high-permittivity dielectric scatterers and extended leaky cavities embedded in a complex environment. We expect our framework to find important applications in the enhancement of light-matter interactions in photonic materials as well as to enhance energy harvesting.
