Switchable Terahertz Beam Steering with Near‐Perfect Ordinary Transmission
Advanced Photonics Research, EarlyView.This study introduces a reconfigurable metasurface that enables switchable terahertz beam steering upon actuation by a global temperature change. At room temperature, it achieves a true “OFF” state with nearly 100% transmission, behaving as if the metasurface is not present, thereby not distorting incoming light.

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review
Advanced Photonics Research, EarlyView.Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective
Advanced Photonics Research, EarlyView.This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View
Advanced Photonics Research, EarlyView.Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities
Advanced Photonics Research, EarlyView.Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.

Early Pancreatic Cancer Diagnosis via Ultrasensitive THz Toroidal Metasensing
Advanced Photonics Research, EarlyView.This study introduces a revolutionary terahertz metasurface biosensor using gold nanoparticles to boost sensitivity. It achieves precise detection of ultra‐low biomarker concentrations (1–1000 pg mL−1) with a 97.6 GHz/RIU sensitivity through optimized antibody binding.
