Submicrosecond Electric Switching of Large Birefringence in the Isotropic Phase of Ferroelectric Nematics

Advanced Optical Materials, EarlyView.
We demonstrate ultra‐fast and efficient electro‐optical switching using the isotropic phase of ferroelectric nematic liquid crystals. A moderate electric field induces a transition to polar ferroelectric nematic order, producing large field‐induced birefringence with sub‐microsecond switch‐on and switch‐off times. This advance enables new opportunities

Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking

Advanced Photonics Research, EarlyView.
Giant second‐harmonic generation (SHG) susceptibility, on the order of 1000 pm V−1, in SnSe with ferroelectric stacking is demonstrated by theoretical and experimental methods. SHG microscopy is utilized to study few‐layer ferroelectric SnSe flakes on mica substrates. Stripe‐like features in SHG mapping indicate ferroelectric domains. Strong wavelength‐

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 ...

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons

Advanced Photonics Research, EarlyView.
Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.
