Effects of absorption and inhibition during grating formation in photopolymer materials [PDF]

, 2006
Photopolymer materials are practical materials for use as holographic recording media, as they are inexpensive and self-processing (dry processed). Understanding the photochemical mechanisms present during recording in these materials is crucial to ...

Revealing the Transmission Hologram's Refractive Index Profile Stored in a Photohydrogel: A Structural Characterization

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery

Advanced Optical Materials, Volume 14, Issue 28, 24 July 2026.
Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Stress‐guided photo‐programming of cholesteric liquid crystal elastomers for 2D‐to‐3D shape–color information encoding

Responsive Materials, Volume 4, Issue 2, May 2026.
We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
