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.

Data from NE Times shows that LiDAR installations in Chinese passenger vehicles reached 525,500 units in August 2026. Hesai installed 182,436 units, just 65 fewer than Huawei, and the two together accounted for 69.4%. The growth logic is extending beyond simply adding vehicle models to multiple LiDARs per vehicle, robot perception and 3D spatial mapping.
Why we recommend it: The original paper provides monthly installation and market share data, useful for assessing the automotive LiDAR market landscape
