Researchers have developed and demonstrated a GaP-on-diamond hybrid nanophotonic platform enabling controlled interaction between photons and silicon-vacancy (SiV) centers in diamond. Using stamp transfer, the team fabricated more than 600 nanophotonic cavities on a diamond substrate with a yield of 99.5%, achieving cooperativity above 1 and a spin relaxation time exceeding 0.4 milliseconds, enabling single-shot readout of SiV electron spins. Next steps include connecting multiple devices on the same chip and demonstrating entanglement.

A review article in Light: Science & Applications describes sliding metasurfaces developed by H. Shi, W. Zhu, G. Hu and colleagues. Relative lateral displacement of 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 that depend on active components, and could extend to terahertz and optical bands.
Why we recommend it: The article contrasts tunable metasurfaces that rely on active components such as PIN diodes, explaining the idea of replacing per-unit cell control with interlayer translation.
Researchers integrated gallium phosphide (GaP) nanophotonic cavities onto a diamond substrate using a stamp transfer process, enhancing quantum optical interaction with diamond color centers.
