Chip-Scale Brillouin Laser Gyroscope Measures Rotation Down to 37 Degrees per Hour
Start here
The Optica news center reported that a team from UCSB and Caltech published a chip-scale optical ring laser gyroscope in Optics Letters, capable of measuring rotation as low 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 on 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. Phys.org subsequently followed up with a report on the integrated Brillouin laser ring gyroscope, likewise noting that it can measure rotation rates as low as 37 degrees per hour.
