From Invisible to Visible: Pressure‐Responsive Photonic Crystals for Advanced Information Encryption

Advanced Optical Materials, EarlyView.
Multilayered composite materials are fabricated based on chiral nematic cellulose nanocrystals incorporated in a shape‐memory polymer matrix. Upon hot‐pressing, they consistently present initially hidden patterns/information with structural colors distinct from the background over multiple pressing‐recovery cycles.

Coherent Control of Thermal Radiation with Nanophotonics

Advanced Photonics Research, EarlyView.
This review explores the innovative control of thermal radiation coherence using nanophotonic structures. The fundamentals of thermal radiation, coherence control strategies (temporal, spatial, and polarization), and their applications in infrared sensing, radiative cooling, thermal camouflage, and imaging, are discussed.

Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, EarlyView.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

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.
