Aerosol Jet Printed Polymer‐Free High Aspect Ratio Quantum Dot Films for Enhanced Color Conversion

Advanced Optical Materials, EarlyView.
Polymer‐free quantum dot color conversion layers are aerosol jet printed at high aspect ratio by tuning the aerosol focus ratio to induce in‐flight droplet drying. Contact‐line pinning suppresses lateral spreading, enabling ∼10 µm‐thick films at ∼50 µm widths with blue light leakage below 0.25% and conversion efficiency approaching 18%, demonstrated ...

Coherent control of photonic spin Hall effect in a cavity

Optics Express
This paper theoretically investigates the manipulation of the photonic spin Hall effect (photonic SHE) using a four-level closed coherent control coupling scheme in a cavity. The atomic system is configured to function as a combined Tripod and Lambda (CTL), Lambda Λ, and N-level model by properly adjusting the control field strengths and their relative

Non-Hermitian Spin-Hall Effect in Topological Metasurfaces

, 2023
We demonstrate that, for suitable trapping one-dimensional Dirac potentials, there exist guided modes exhibiting spin-dependent field distributions, which may give rise to their different coupling efficiency to the radiative continuum or light-matter ...

Polarization manipulation of giant photonic spin Hall effect using wave-guiding effect

, 2022
In plasmonic systems, the enhanced photonic spin Hall effect (PSHE) was previously possible only for horizontal polarization. By employing the wave-guiding surface plasmon resonance (WG-SPR) effect, we report a giant photonic spin Hall effect (G-PSHE) of
