Abstract
Enhancing the skin effect in non-Hermitian photonic crystals has traditionally required alternating materials with different gain and loss characteristics inside the basic unit, which not only increases fabrication complexity but also faces limitations due to different material compatibility and material integrations. In this paper, a novel method is proposed that requires only one material but enables significant enhancement of the skin effect intensity by introducing spatial rotational symmetry breaking in two-dimensional reciprocal photonic crystals. Our result has shown a 306.09% improvement in skin effect intensity with just one material, if compared to previous designs. Our finding not only may broaden the theoretical framework of non-Hermitian optics but also demonstrates significant potential for practical applications in photonic integration, optical sensing, and laser design, thus opening up new possibilities for future photonic device innovations.
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.
