摘要:

原子级薄的黑磷(BP)是一种新兴的二维(2D)材料,在近红外区表现出明亮的光致发光。将其辐射耦合到光子纳米结构将是实现基于2D材料的纳米光子器件的重要一步,该器件在近红外线中有效地工作,其中包括技术上重要的光通信波长波段。在这封信中,我们演示了原子薄BP和二维光子晶体纳米腔之间的光学耦合。我们采用自制的干转移装置将薄BP薄片放置在纳米腔的表面上。通过测量室温下光载流子注入下的腔模发射,分析了它们之间的光耦合。

英文摘要:

Atomically-thin black phosphorus (BP) is an emerging two dimensional (2D) material exhibiting bright photoluminescence in the near infrared. Coupling its radiation to photonic nanostructures will be an important step toward the realization of 2D material based nanophotonic devices that operate efficiently in the near infrared, which includes the technologically important optical telecommunication wavelength bands. In this letter, we demonstrate the optical coupling between atomically-thin BP and a 2D photonic crystal nanocavity. We employed a home-build dry transfer apparatus for placing a thin BP flake on the surface of the nanocavity. Their optical coupling was analyzed through measuring cavity mode emission under optical carrier injection at room temperature.
