Efficient Cholesteric Liquid Crystal Waveguide Polarizing Splitters for High‐Sensitivity Chip‐Scale Atomic Magnetometry

open access: yesAdvanced Science, EarlyView.
An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition

open access: yesSmall, EarlyView.
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]

open access: yes, 2002
The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].

Synthesis of Chiral Gold Nanostructures on Gold‐Coral‐Coated Transparent Conductive Oxide Substrates via [AuCl4]– and Cysteine Interactions for Enhanced Chiral Sensing

open access: yesSmall, EarlyView.
We developed hierarchical chiral Au nanostructures on Au coral structures on transparent conductive oxide substrates using only electrochemical methods. By controlling the interaction between [AuCl4]– and cysteine, we successfully tuned the morphology and circular dichroism of the resulting Au nanostructures.
