Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

open access: yesAdvanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.

A Single‐Solvent Acetone Strategy for Surface Enhancement and Robust Bonding in PMMA Microfluidic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
A single‐solvent acetone strategy simultaneously restores laser‐ablated PMMA surfaces and enables high‐strength bonding for microfluidic device fabrication. The process produces smooth, optically clear channels, achieves bonding strengths up to 27.3 MPa, and forms leak‐free devices within 25 min, providing a rapid and accessible route to robust PMMA ...

Spectral Compensation Strategy for Radical‐Induced Dye Degradation in Liquid Crystal Polymer Composites

open access: yesAdvanced Optical Materials, EarlyView.
A spectral compensation strategy is introduced to overcome radical‐induced degradation of dichroic dyes during UV photopolymerization. By incorporating a complementary photochromic liquid‐crystalline dye, broadband optical attenuation is preserved without disrupting photopolymerization, enabling high‐contrast and durable dye‐doped liquid crystal ...

Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals

open access: yesAdvanced Optical Materials, EarlyView.
Ion‐driven electrohydrodynamic effects enable dynamic photonic bandgap modulation in cholesteric liquid crystals under low‐frequency AC driving. By regulating ion‐mediated disturbance of the helical structure, this approach produces two reversible optical responses: rapid color shifting across the visible spectrum and broadband reflection spanning the ...

Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams

open access: yesAdvanced Optical Materials, EarlyView.
Standalone low‐index microscale ridges (MRs) are promising platforms for all‐dielectric structural color generation. They are compact and easy to fabricate, but their color purity trails behind that of resonator‐ or periodic pattern‐based structural color pixels.
