Nonlinear optics with structured light

open access: yesOpto-Electronic Advances, 2022
The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven by the tremendous developments in the toolkit for the creation, control and detection of what is now called structured light.

Optical frequency averaging of light

open access: yesOptics Express, 2023
The use of averaging has long been known to reduce noise in statistically independent systems that exhibit similar levels of stochastic fluctuation. This concept of averaging is general and applies to a wide variety of physical and man-made phenomena such as particle motion, shot noise, atomic clock stability, measurement uncertainty reduction, and ...

Stabilisation of central wavelength of erbium‐doped fibre source as part of high‐accuracy fibre optic gyroscopes

open access: yesIET Optoelectronics, 2021
The stability of the central wavelength of the erbium‐doped fibre source (EDFS) is one of the most important parameters to ensure the accurate operation of navigation systems based on high‐accuracy fibre optic gyroscopes (FOGs).

Enhanced Wind-Field Detection Using an Adaptive Noise-Reduction Peak-Retrieval (ANRPR) Algorithm for Coherent Doppler Lidar

open access: yesAtmosphere, 2023
Wind fields provide direct power for exchanging energy and matter in the atmosphere. All-fiber coherent Doppler lidar is a powerful tool for detecting boundary-layer wind fields.

Harvesting light with transformation optics [PDF]

open access: yesScience China Information Sciences, 2013
Transformation optics (TO) is a new tool for controlling electromagnetic fields. In the context of metamaterial technology, it provides a direct link between a desired electromagnetic (EM) phenomenon and the material response required for its occurrence. Recently, this powerful framework has been successfully exploited to study surface plasmon assisted

Stopping Light All Optically [PDF]

open access: yesPhysical Review Letters, 2004
We show that light pulses can be stopped and stored all-optically, with a process that involves an adiabatic and reversible pulse bandwidth compression occurring entirely in the optical domain. Such a process overcomes the fundamental bandwidth-delay constraint in optics, and can generate arbitrarily small group velocities for light pulses with a given

The phase shift induced by a single atom in free space [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2013
In this article we theoretically study the phase shift a single atom imprints onto a coherent state light beam in free space. The calculations are performed in a semiclassical framework.

Robust speckle-free imaging using random lasers enhanced by TiN nanoparticles in complex scattering environments

open access: yesNanophotonics, 2023
A light source with narrowband, sufficient brightness, and low spatial coherence is required for certain applications such as optical imaging and free-space optical communication.
