Physical meaning of the radial index of Laguerre-Gauss beams [PDF]
, 2015 The Laguerre-Gauss modes are a class of fundamental and well-studied optical fields. These stable, shape-invariant photons - exhibiting circular-cylindrical symmetry - are familiar from laser optics, micro-mechanical manipulation, quantum optics ...

Influence of Image Processing Method on Wavefront Reconstruction Accuracy of Large-Aperture Laser
Photonics, 2023 In order to improve the wavefront reconstruction accuracy of a large-aperture laser, this paper proposed an adaptive window preprocessing algorithm based on the threshold center of gravity method (AW-TCoG).

Geometrical vs wave optics under gravitational waves [PDF]
, 2015 We present some new derivations of the effect of a plane gravitational wave on a light ray. A simple interpretation of the results is that a gravitational wave causes a phase modulation of electromagnetic waves.

Nonlinear and Quantum Optics with Whispering Gallery Resonators [PDF]
, 2016 Optical Whispering Gallery Modes (WGMs) derive their name from a famous acoustic phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This phenomenon has a rather general nature, equally applicable to sound and all other waves.

Scattering of Partially Coherent Vector Beams by a Deterministic Medium Having Parity-Time Symmetry
Photonics, 2022 We study the scattering properties of the partially coherent vector beams with the deterministic media having the classic symmetric and parity-time (PT) symmetric scattering potential functions.

Efficient Classical Simulation of Optical Quantum Circuits [PDF]
, 2002 We identify a broad class of physical processes in an optical quantum circuit that can be efficiently simulated on a classical computer: this class includes unitary transformations, amplification, noise, and measurements.
