Polarization‐Independent Single‐Band Guided‐Mode Resonance InGaAs Photodetector Array for Snapshot Multispectral Sensing

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Here, we report a single‐band guided‐mode resonance (GMR) InGaAs photodetector (PD) array. The device consists of an InGaAs PD with an ultrathin absorption layer bonded onto a Si 2D grating. Although a 2D crossed‐grating inherently supports many more optical modes than a 1D grating, we realized a single‐band response by introducing novel design ...

Decoupled Spectral Tuning and Polarization Locking in Twisted α $\alpha $‐MoO3 Polaritonic Crystals

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
We introduce a deterministic design strategy employing twisted bilayer α $\alpha $‐MoO3 ${\text{MoO}}_{3}$ polaritonic crystals to decouple infrared spectral and polarization degrees of freedom. Although adjusting the interlayer twist angle tunes the absorption spectra, the maximum absorption axis remains robustly locked to the patterned layer's ...

Design of Large‐Aperture Hybrid Refractive Metalens System

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Surrogate Scattering Matrix‐Guided Inverse Design of Nanophotonic Neural Networks

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Surrogate‐guided inverse design separates task learning from electromagnetic realization by transferring a trained passive operator to a fabrication‐aware nanophotonic structure. The electromagnetic cost of each update depends on port count rather than the dataset size.
