Ferroelectric Fluids for Nonlinear Photonics: Evaluation of Temperature Dependence of Second‐Order Susceptibilities

open access: yesAdvanced Optical Materials, EarlyView.
Nonlinear optical susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as smectic A ferroelectric phase, are determined. The materials investigated include archetypal molecular architectures as well as mixtures showing room‐temperature ferroelectric phases.

Photonics of Topological Magnetic Textures

open access: yesAdvanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology

open access: yesAdvanced Optical Materials, EarlyView.
A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.
