Abstract

We demonstrate a chip-scale ring-laser gyroscope on a CMOS-ready Si₃N₄ platform, achieving sensed rotation approaching the Earth's rotation rate. The device is based on counter-propagating Brillouin lasers that convert rotation into a Sagnac-induced frequency shift. To our knowledge, this is the first demonstration of an actual measurement near the Earth's rotation rate on a photonic-chip-integrated platform, marking a significant step toward fully integrated optical gyroscopes.

集成微谐振布里渊陀螺仪显示37度/小时的旋转测量。

我们展示了一个芯片级环形激光陀螺仪在cmos ready Si3N4平台上，实现了接近地球自转速率的感测旋转。该装置基于反向传播布里渊激光器，将旋转转换为萨格纳克诱导的频移。据我们所知，这是第一次在光子芯片集成平台上实际测量接近地球自转速率的演示，标志着向完全集成光学陀螺仪迈出了重要的一步。

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.
