摘要

从纳米光子学到量子通信,在强耦合机制下运行的光物质相互作用具有广阔的应用前景。最实用的实现方法是将有源物质嵌入法布里-珀罗微腔或光子晶体。在这项工作中,我们重点研究了一维光栅波导中二维(2D)包晶的强耦合。我们使用严格的耦合波分析来模拟一维波导中的电磁波约束。我们研究了各种波导几何参数集,以实现波导中活性层三种不同配置的强耦合机制。为了定量提取相关的物理参数,如光-物质相互作用的强度,我们建立了一个哈密顿形式主义来重现模拟得到的结果。结果表明,最强烈的相互作用是将有源层插入波导的主板。然而,与使用法布里-珀罗微腔相比,它仍然要弱 20%左右。

A comparative simulation study of light–matter coupling in 1D photonic crystals with 2D perovskite active layer

Light–matter interaction operating in the strong coupling regime offers wide prospects of applications going from nano-photonics to quantum communications. The most practical implementations are to embed the active matter into Fabry–Perot microcavities or photonic crystals. In this work we focus on the strong coupling of two-dimensional (2D) perovskite in 1D grating waveguide. We use rigorous coupled wave analysis to simulate electromagnetic wave confinement in the 1D waveguide. Various sets of waveguide geometrical parameters are examined to achieve the strong coupling regime for three different configurations of the active layer in the waveguide. To extract quantitatively the relevant physical parameters, such as strength of light–matter interaction, we develop a Hamiltonian formalism to reproduce results obtained by simulation. It is shown that the strongest interaction is to have the active layer inserted in the main slab of the waveguide. It is, however, still weaker by about 20% as compared to the use of Fabry–Perot microcavities.

期刊介绍: In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
