    Gallium Phosphide-Diamond Hybrid Platform Enhances Quantum Light-Matter Interaction

    Researchers integrated gallium phosphide (GaP) nanophotonic cavities onto a diamond substrate using a stamp transfer process, enhancing quantum optical interaction with diamond color centers. The devices are first fabricated by electron-beam lithography in a GaP thin film on a carrier, screened by spectroscopic testing, and then transferred. Experiments achieved cooperativity above 1. The platform can serve as a light-matter interface in quantum networks.

    Why we recommend it: The source details the heterogeneous integration process and the screening-and-transfer workflow, offering useful reference for fabrication routes for diamond color center quantum photonic devices.

    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.
