A review article in Light: Science & Applications presents the sliding metasurface developed by H. Shi, W. Zhu, G. Hu and colleagues. Relative lateral displacement between two complementary metasurface layers generates an effective phase gradient, enabling passive beam steering while retaining frequency-selective filtering. The authors argue that this geometry-driven passive approach is simpler and more scalable than tunable metasurfaces dependent on active components, and could be extended to the terahertz and optical bands.
Why we recommend it: The article contrasts tunable metasurfaces that rely on active components such as PIN diodes, highlighting the idea of replacing per-unit-cell control with interlayer translation.
Researchers integrated gallium phosphide (GaP) nanophotonic cavities onto diamond substrates via a stamp-transfer process, enhancing quantum optical interactions with diamond color centers. The devices were first fabricated in a GaP thin film on a carrier using electron-beam lithography, screened spectroscopically, and then transferred; the experiments achieved cooperativity greater than 1. The platform could serve as a light–matter interface in quantum networks.
Why we recommend it: The original article describes the heterogeneous integration process and the screening-and-transfer workflow, offering useful guidance for fabricating diamond color-center quantum photonic devices.
Optics & Photonics News reports that an early clinical study showed optogenetic therapy can partially restore vision in patients with severe vision loss. Most adverse events were mild to moderate, with only one transient severe event after injection that resolved within minutes. First author José-Alain Sahel of the University of Pittsburgh said the results show that the visual system retains the ability to process new information even in people with severe blindness.
Why we recommend it: Optogenetic therapy applies light stimulation directly to vision restoration, and the original article provides safety results from an early clinical study, serving as a reference for biophotonics applications
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.
Why we recommend it: That is nearly a 2,000-fold improvement over the team's earlier silicon nitride Brillouin gyroscope, which measured 72,000 degrees per hour, and indicates how far on-chip optical gyroscopes still are from navigation-grade applications.
