Abstract

We report a narrow-linewidth laser based on thin-film lithium tantalate (TFLT). The laser is composed of an InP reflective semiconductor optical amplifier gain chip hybrid integrated with a TFLT waveguide external cavity cladded with a silicon oxide extended Bragg grating. The single-frequency laser device achieves an on-chip output power of approximately 26 mW and an intrinsic Lorentzian linewidth of ~94 Hz. These results highlight the great potential of TFLT for integrated photonic laser applications, enabling high-coherence and high-power laser sources in a compact platform.

窄线宽片上III-V/TFLT激光器。

我们报道了一种基于薄膜钽酸锂（TFLT）的窄线宽激光器。该激光器由InP反射半导体光放大器增益芯片与包覆氧化硅扩展布拉格光栅的TFLT波导外腔混合集成而成。该单频激光器件的片上输出功率约为26 mW，固有洛伦兹线宽约为94 Hz。这些结果突出了TFLT在集成光子激光应用中的巨大潜力，在紧凑的平台上实现高相干和高功率激光源。

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.
