On the exploration of periodic wave soliton solutions to the nonlinear integrable Akbota equation by using a generalized extended analytical method [PDF]

open access: yesScientific Reports
In the present study, we explored the optical solitons with novel physical structure in the nonlinear Akbota equation on the enhancement of extended analytical approach. The nonlinear Akbota equation having enriched applications in physics, such as fiber

Deterministic Optical Rogue Waves [PDF]

open access: yesPhysical Review Letters, 2011
Experimental observations of rare giant pulses or rogue waves were done in the output intensity of an optically injected semiconductor laser. The long-tailed probability distribution function of the pulse amplitude displays clear non-Gaussian features that confirm the rogue wave character of the intensity pulsations.

Effect of Wind Transport of Turbulent Inhomogeneities on Estimation of the Turbulence Energy Dissipation Rate from Measurements by a Conically Scanning Coherent Doppler Lidar

open access: yesRemote Sensing, 2020
A method for estimation of the turbulent energy dissipation rate from measurements by a conically scanning pulsed coherent Doppler lidar (PCDL), with allowance for the wind transport of turbulent velocity fluctuations, has been developed.

Anisotropic Airy beams

open access: yesResults in Optics, 2023
Anisotropic Airy beams are presented as solutions to the parabolic wave equation. We obtain the cross polarization terms in the new beams using the elegant Mukunda–Simon–Sudarshan matrix substitution rule for transition from Helmholtz scalar wave optics ...

A matrix differential operator for passage from scalar to vector wave optics

open access: yesResults in Optics, 2023
One possible way to generalize scalar to wave optics, thus including polarization in the treatment consistent with the Maxwell equations was shown by Mukunda, Simon and Sudarshan (MSS) for paraxial systems, based on a group theoretical analysis.

The singularities of light: intensity, phase, polarisation

open access: yesLight: Science & Applications, 2023
In modern optics, light can be described at different levels: as rays, as scalar waves, as vector fields, and as quantum fields. In the first three levels, there are singularities—characteristic features, useful in interpreting phenomena at that level ...
