摘要

在这项工作中，我们提出了一种控制和调节异常点（EPs）强度及其向恶魔点（dp）转变的光子方案。所提出的方案利用特殊的表面几何形状与标准马赫-曾德尔干涉仪相结合来创建一个可调谐的反射镜。通过全波模拟验证了该结构的功能，展示了其动态操纵EPs和DPs的潜力。重要的是，我们的方案可以使用标准片上光子学技术来实现。

Tuning the strength of exceptional points and their transition to diabolic points.

In this work, we present a photonic scheme for controlling and tuning the strength of exceptional points (EPs) and their transition to diabolic points (DPs). The proposed scheme utilizes exceptional surface geometry in conjunction with a standard Mach-Zehnder interferometer to create a tunable mirror. The functionality of this structure is validated through full-wave simulations, demonstrating its potential for the dynamic manipulation of EPs and DPs. Importantly, our scheme can be implemented using standard on-chip photonics technology.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
