Brillouin scattering in hollow-core fibers filled with mixed gas.
Brillouin scattering in gas-filled hollow-core fibers (HCFs) is significantly enhanced by the strong light-gas interaction and the tunability of gas properties by the hollow-core structure. However, the behavior of Brillouin scattering in HCFs filled with mixed gas remains unexplored. In this work, we present the first, to the best of our knowledge, investigation of backward Brillouin scattering in HCF waveguides filled with mixed gas. We examine its dependence on pressure, temperature, and gas composition, developing a theoretical model that aligns well with experimental results. Furthermore, we demonstrate that the Brillouin spectrum can be tuned via gas concentration and pressure, offering new possibilities for controlling Brillouin interactions in gas-filled waveguides.
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.
