Cryogenic Dielectric Metasurface‐Integrated Superconducting Nanowire Single‐Photon Detectors

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Superconducting nanowire single‐photon detectors (SNSPDs) are the leading technology for single‐photon detection because of their near‐unity system detection efficiency, ultrahigh timing precision, and very low dark counts. However, achieving these performance metrics with single element, small‐active‐area SNSPDs has been an outstanding challenge. Here,

Cross‐Scale Synergistic Optimization for Miniature Meta‐Liquid Hybrid Zoom Imaging

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A physically constrained optimization framework links electrowetting liquid lenses and metasurface dispersion engineering to realize a compact visible‐band achromatic zoom imager. By co‐optimizing zoom actuation, meta‐atom manufacturability, and system aberrations, the design achieves 1.5x zoom in a 15.5 mm track and clarifies robustness against ...
