Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Lossless Compression of Hyperspectral Image Based on Spatial-Spectral Hybrid Prediction

, 2008
This paper proposes an improved lossless compression algorithm based on the spatial-spectral hybrid prediction. We choose the prediction modes between the spatial and the spectral domains by computing the local correlation coefficient.

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...
