Chip-Scale Optical Ring Laser Gyroscope Detects Slow Rotation of 37 Degrees per Hour

A team from UCSB and Caltech has published an account in Optics Letters of 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 built on a silicon nitride waveguide photonic integrated circuit, can be fabricated with standard CMOS processes, and requires only milliwatt-level optical power. Its sensitivity is nearly 2,000 times better than the team's earlier device.

ASML Studies Further Expanding Lithography Capacity as Chip Demand Keeps Growing

ASML said its existing 2027 and 2028 supply plans cannot fully meet customer demand and that it is studying a further expansion of 2028 capacity beyond the previously planned 30% increase. Quarterly sales through September 27 reached €11.7 billion, up more than 50% year on year. The NXE:3800F EUV lithography system slated for introduction next year will raise productivity from 230 to 260 wafers per hour.

Self-Aligned Dual-Pump Scheme Opens New Path for Optical Frequency Combs
