Manipulating optical properties of MXene/TiN with strong nonmetallic plasmonic coupling for multifunctional imaging attenuation

InfoMat, EarlyView.
Plasmonic materials enable flexible optical manipulation owing to their unique plasmon resonance, making them highly promising for photoelectronic imaging attenuation. This study theoretically designed and experimentally prepared a unique dual nonmetallic plasmonic Ti3C2Tx/TiN hybrid.

Fast‐switchable polarization‐dependent bifocal lenses for AR displays

Journal of the Society for Information Display, EarlyView.
Polarization‐dependent bifocal Pancharatnam‐Berry phase lenses, fabricated via photoalignment, integrate bifocal functionality for AR displays. An electrically suppressed helix ferroelectric liquid crystal polarization rotator enables rapid switching (35 μs) between dual depths or field‐of‐views (FOVs) in longitudinal and transverse configurations ...

Coherence Awareness in Diffractive Neural Networks

Laser &Photonics Reviews, EarlyView.
It is demonstrated that spatial coherence significantly impacts all‐optical diffractive neural networks, unlike imaging systems. A general framework is proposed for training diffractive networks for any specified degree of spatial and temporal coherence. Coherence‐blind networks are further introduced, which are resilient to illumination changes. These

Silicon‐Integrated Perovskite Photonic Laser Based on Bound States in Continuum

Laser &Photonics Reviews, EarlyView.
A strategy to integrate perovskite coherent light sources onto commercial silicon platform is proposed. Based on the bound states in the continuum, the energy leakage from perovskite microdisk to silicon is totally removed, leading to the observation of perovskite lasers on silicon with a laser quality factor ∼4850.
