Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Projective filtering of a single spatial radiation eigenmode

open access: yes, 2015
Lossless filtering of a single coherent (Schmidt) mode from spatially multimode radiation is a problem crucial for optics in general and for quantum optics in particular.

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

open access: yesLaser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Multiwavelength Single-Longitudinal-Mode Brillouin–Erbium Fiber Laser Sensor for Temperature Measurements With Ultrahigh Resolution

open access: yesIEEE Photonics Journal, 2015
A multiwavelength single-longitudinal-mode (SLM) Brillouin-erbium fiber laser sensor with ultrahigh resolution is proposed and investigated experimentally. The one short common cavity with 50 m of single mode fiber (SMF) as the fiber under test and 100 m

A Single-Mode Erbium Fiber Laser With Flat Power Output and Wide Wavelength Tunability

open access: yesIEEE Photonics Journal, 2020
In this research, we present and study an erbium fiber laser with triple-fiber-ring (TFR) scheme for continuous-wave (CW) wavelength-selection. The designed TFR not only can achieve single-longitudinal-mode (SLM) oscillation, but also can spread the ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Detection of Bessel beams with digital axicons

open access: yes, 2014
We propose a simple method for the detection of Bessel beams with arbitrary radial and azimuthal indices, and then demonstrate it in an all-digital setup with a spatial light modulator.

Increased expression of aromatase after focal cerebral ischemia: Relevance to neuroprotection and functional recovery

open access: yesNeuroprotection, EarlyView.
Abstract Aim Aromatase is the key enzyme in the biosynthesis of 17β‐estradiol, the most potent estrogen, which has pleiotropic neuroprotective properties. Aromatase levels increase in the brain after stroke, and its gene variants increase susceptibility to stroke. This study aims to determine whether aromatase overexpression improves stroke outcome and
