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.

Chip Demand Keeps Growing; ASML Studies Further Expanding Lithography Equipment Capacity

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 were EUR 11.7 billion, up more than 50% year over year. The NXE:3800F EUV lithography system slated for introduction next year will raise productivity from 230 to 260 wafers per hour.
