The Design of a Circulator Based on Topological Photonic Crystals

Photonics
Topological photonic crystals have garnered significant attention due to their fascinating topological edge states. These states are robust against sharp bends and defects and exhibit the novel property of unidirectional transmission.

Evaporation Kinetics Engineering Suppressed Bimolecular Recombination in All‐Polymer Solar Cells

Advanced Science, EarlyView.
In this study, phenanthrene (Ph), a volatile solid additive with a weak tendency toward self‐aggregation, is introduced as a donor‐selective morphology regulator in benchmark all‐PSC systems. The moderate evaporation kinetics of Ph enable cooperative crystallization of donors and acceptors, leading to an increased fractal dimension with reduced donor ...

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

Open‐Shell Conjugated Polymers Enable Photothermoelectric Conversion and Detection of Short‐Wave Infrared Light

Advanced Science, EarlyView.
Efficient conversion and detection of short‐wave infrared (SWIR) photons are becoming increasingly important for emerging photonic and energy technologies. Here, we report an organic photothermoelectric device based on an open‐shell conjugated polymer that enables SWIR energy conversion and photon detection via the photothermoelectric effect.

Resonant spin Hall effect of light in random photonic arrays

SciPost Physics, 2023
It has been recently shown that the coherent component of light propagating in transversally disordered media, the so-called coherent mode, exhibits an optical spin Hall effect (SHE).

Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

Advanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Photonic spin Hall effect enabled highly sensitive pressure sensor.

Optics Express
In this work, we propose a high-sensitivity pressure sensing platform exploiting the photonic spin Hall effect (PSHE), where pressure-induced refractive index modulations of the sensing medium induce quantifiable spin-dependent beam displacements.

First Experimental Observation of Photonic Spin Hall Effect in Hyperbolic Metamaterials at Visible Wavelengths

, 2019
The photonic spin Hall effect [1] or spin Hall effect of light [2] is the photonic analog of the spin Hall effect occurring with charge carriers in solid-state systems.
