Abstract

Atomically layered van der Waals (vdW) materials exhibit remarkable properties, including highly confined infrared waveguide modes and the capacity for infrared emission in the monolayer limit. Here we engineered structures that leverage both of these nano-optical functionalities. Specifically, we encased a photoluminescing atomic sheet of MoTe2 within two bulk crystals of WSe2, forming a vdW waveguide for the embedded light-emitting monolayer. The modified electromagnetic environment offered by the WSe2 waveguide alters MoTe2 spontaneous emission—a phenomenon we directly image with our interferometric nano-photoluminescence technique. We captured spatially oscillating nanoscale patterns prompted by spontaneous emission from MoTe2 into waveguide modes of WSe2 slabs. We quantify the resulting Purcell-enhanced emission rate within the framework of a waveguide quantum electrodynamics model, relating the MoTe2 spontaneous emission rate to the measured waveguide dispersion. Our work marks a substantial advance in the implementation of all-vdW quantum electrodynamics waveguides. A nano-optical probe of the Purcell effect in a van der Waals waveguide is demonstrated, exploiting its highly confined infrared waveguide modes and the capacity for infrared emission in the monolayer limit of atomically layered van der Waals materials.

红外纳米光致发光探测范德华波导量子电动力学

原子层状范德瓦尔斯（vdW）材料表现出优异的性能，包括高度受限的红外波导模式和单层极限下的红外发射能力。在这里，我们设计了利用这两种纳米光学功能的结构。具体来说，我们将MoTe2的光致发光原子片包裹在两个WSe2块状晶体中，为嵌入的发光单层形成了vdW波导。WSe2波导提供的修改电磁环境改变了MoTe2的自发发射，这是我们用干涉纳米光致发光技术直接成像的现象。我们捕获了由MoTe2自发发射到WSe2板波导模式引起的空间振荡纳米尺度图案。我们在波导量子电动力学模型的框架内量化了purcell增强的发射率，将MoTe2自发发射率与测量的波导色散联系起来。我们的工作标志着全vdw量子电动力学波导的实现取得了实质性进展。
