Polarization-indipendent Kerr coefficient measurement in optical fiber

, 1996
A novel cross-phase modulation scheme that permits measurement of the optical Kerr coefficient in nonpolarization-preserving fiber is presented. The scheme is based on a Michelson-type interferometer in which one mirror is replaced by an orthoconjugated ...

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]

, 2012
We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.

Electrocatalytic CO2 Reduction over Sn‐Cu Bimetallic Catalysts Synthesized via an Amalgamated Lithium Metal Method

Advanced Science, EarlyView.
An amalgamated lithium metal method enables systematic control of Sn–Cu active‐site dimensions from isolated atoms to nanocrystallites. Increasing the metal loading shifts CO2 electroreduction selectivity from acetaldehyde on highly dispersed Sn–Cu sites to formate on Sn‐rich crystallites, revealing how bimetallic dispersion and local coordination ...

Single‐Dose TACE‐Like Injection of Sustained‐Release Panobinostat/IL‐12 Polymeric Microparticles is Effective in Preclinical Liver Cancer Models

Advanced Science, EarlyView.
A novel PLGA/PBAE polymer microparticle platform revolutionizes intermediate‐stage liver cancer treatment by co‐delivering panobinostat and IL‐12 via a single TACE‐like injection. This sustained‐release system overcomes tumor immunosuppression, triggers robust innate and adaptive immune responses, and establishes tertiary lymphoid structures ...

Colorimetric and Near-Absolute Polarization-Insensitive Refractive-Index Sensing in All-Dielectric Guided-Mode Resonance Based Metasurface

Journal of Physical Chemistry C, 2019
Colorimetric detection of target molecules with insensitivity to incident-light polarization has attracted considerable attention in recent years. This resulted from the ability to provide rapid output and reduced assay times as a result of color changes

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

Advanced 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 ...

Photoactivation‐Enabled Tunable Room‐Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials

Advanced Science, EarlyView.
This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,

Twin‐Lever Multifunctional Meta‐Optics With High Longitudinal Tolerance

Advanced Science, EarlyView.
We introduce a single‐layer, CMOS‐compatible metasurface that allows for polarization‐programmable, achromatic broadband dual‐mode imaging with high longitudinal tolerance. The twin‐lever design combines bright‐field focusing and vortex‐based edge‐enhanced imaging while managing axial intensity distribution from 488 to 633 nm.
