Optical fibers offer convenient access to a variety of nonlinear phenomena. However, due to their inversion symmetry, second-order nonlinear effects, such as second-harmonic generation (SHG), are challenging to achieve. Here, all-
This study investigates the influence of seismic activities on the optical synchronization system of the European X-ray Free-Electron Laser. We analyze the controller input/output data of phase-locked loops in length-stabilized li
The growing demand for broadband near-infrared (NIR) irradiation in security, biomedicine, and food science is driving the development of new NIR light sources. Herein, a series of Cr3+/Ni2+ co-doped transparent glass ceramics con
Photon-level single-pixel imaging overcomes the reliance of traditional imaging techniques on large-scale array detectors, offering the advantages such as high sensitivity, high resolution, and efficient photon utilization. In thi
The degradation of image quality in space-based remote sensing is a critical challenge due to atmospheric disturbances. In this paper, we propose a new model to simulate image blur effects caused by turbulence and aerosol scatteri
Based on the first-order correlation function of light, we propose analogous optical coherent states (AOCSs) sourced by partially coherent beams, which can nondiffractively propagate with sinusoidal oscillation in the harmonic pot
The article provides information about the image on the cover of Advanced Photonics,...
Low-Earth orbit, the primary operational domain for the international space station and commercial satellites, presents a severe thermodynamic environment for spacecraft. Current testing methodologies, such as thermal cycling and
An object or system is said to be chiral if it cannot be superimposed on its mirror reflection. Chirality is ubiquitous in nature, for example, in protein molecules and chiral phonons—acoustic waves carrying angular momentum—which
