    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.

    Russell Center and Partners Report in Optica: Hollow-Core Photonic Crystal Fiber Enables Flexible Delivery of Near-Watt, Hundred-Femtosecond 2.8 µm Mid-Infrared Pulses

    The Russell Advanced Lightwave Science Center at the Hangzhou Institute of Optics and Mechanics, together with the Hangzhou Institute for Advanced Study of UCAS, the Shanghai Institute of Optics and Mechanics, and IRFIBER (Ningbo) Optoelectronics Co., Ltd., published a paper in Optica on delivering near-watt, hundred-femtosecond mid-infrared pulses in the 2.8 µm band through a 5 m-long hollow-core photonic crystal fiber with a single-core, eight-ring structure. After evacuation, overall efficiency exceeded 70%, the output was a near-diffraction-limited Gaussian spot, and the fundamental-mode energy fraction exceeded 95%.

    Why we recommend it: The paper gives efficiency, pulse duration, peak power and fundamental-mode fraction, and compares the fiber with free-space optics and solid-core fluoride fiber, making it easier to judge the applicability of hollow-core fiber to mid-infrared ultrafast delivery.
