Phase Multiplexed Optical Computing: Reconfiguring a Multi‐Task Diffractive Optical Processor Using Illumination Phase Diversity

Laser &Photonics Reviews, EarlyView.
A monochrome multi‐task diffractive optical network architecture is designed to leverage illumination‐phase multiplexing to dynamically reconfigure its output function and accurately implement a large set of complex‐valued linear transformations between an input and an output aperture.

Effect of Horizontal AC Electric Field on the Stability of Natural Convection in a Vertical Dielectric Fluid Layer

Journal of Applied Fluid Mechanics, 2016
The stability of buoyancy-driven parallel shear flow of a dielectric fluid confined between differentially heated vertical plates is investigated under the influence of a uniform horizontal AC electric field.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

Laser &Photonics Reviews, EarlyView.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Activation and Detection of Forbidden Low‐Frequency Raman Modes in MoS2 by Near‐Field Gradient Illumination

Laser &Photonics Reviews, EarlyView.
Low‐frequency Raman‐forbidden interlayer phonons in 2D materials are typically hidden by selection rules. Here, we demonstrate that plasmonic near‐field gradients can activate and detect these forbidden low‐frequency modes in a few‐layer MoS2 sample, unveiling a gradient‐driven mechanism for revealing hidden interlayer vibrations and breaking symmetry.

Calibration‐Free Single‐Frame Super‐Resolution Fluorescence Microscopy

Laser &Photonics Reviews, EarlyView.
A deep learning framework reconstructs super‐resolved fluorescence images from a single dense camera frame, without any prior calibration or knowledge of the microscope. Trained solely on synthetic data, it generalizes across imaging setups and conditions.
