    Chip-Scale Optical Ring Laser Gyroscope Measures Slow Rotations of 37 Degrees per Hour

    A team from UC Santa Barbara and Caltech published in Optics Letters a chip-scale optical ring laser gyroscope capable of measuring rotations as slow as 37 degrees per hour, approaching Earth's rotation rate of 15 degrees per hour. The device is based on a low-noise Brillouin laser in a silicon nitride waveguide photonic integrated circuit, can be fabricated with standard CMOS processes, requires only milliwatt-level optical power, and offers nearly 2,000-fold higher sensitivity than the team's earlier device.

    Why we recommend it: Compared with the team's earlier silicon nitride Brillouin gyroscope rated at 72,000 degrees per hour, this is nearly a 2,000-fold improvement, helping gauge how far on-chip optical gyroscopes are from navigation applications.

    Changchun Institute of Optics, Fine Mechanics and Physics Dual-Modal Neuromorphic Device Uses Optical Signals to Boost Machine Olfaction Gas Classification Accuracy

    A team led by researcher Li Shaojuan at the Changchun Institute of Optics, Fine Mechanics and Physics has developed a vision-olfaction dual-modal neuromorphic device based on a MoS2/SnS2 floating-gate heterostructure. The device responds to both optical and gas signals and fuses them at the device level. The results were published in Advanced Materials. The device has an active area of 148 µm² and static power consumption of 3.4 µW. With the optical modality introduced, classification accuracy for 12 gases rose from 52.24% to 98.27%, while recognition accuracy for 51 gas mixtures reached 89.32%.

    Liutong Photonics Integrated Sensing and Communications Equipment Powers Digital Track at the 15th National Games

    Guangdong Telecom, Sun Yat-sen University, and the Su Bingtian Speed Research and Training Center, among others, used integrated sensing and communications equipment and a digital twin system from Liutong Photonics, a company incubated by the Hangzhou Institute of Optics and Fine Mechanics, to build a digital track based on communication optical fiber and a smart transportation demonstration project around the venue. The system captures vibration signals through hundreds of meters of fiber laid beneath the track and uses AI algorithms to calculate stride length, ground contact time, and other parameters, while the traffic sensing network extracts vehicle speed, trajectories, and traffic density from urban communication fiber cables.
