[HTML][HTML] Temporal Fresnel diffraction induced by phase jumps in linear and nonlinear optical fibres

A Sheveleva, C Finot - Results in Physics, 2020 - Elsevier
We analytically and numerically study the temporal intensity pattern emerging from the linear
or nonlinear evolutions of a single or double phase jump in an optical fiber. The results are …

Fresnel diffraction is a basic quantum mechanical effect

MT Tavassoly - JOSA B, 2021 - opg.optica.org
Using the Fresnel–Kirchhoff integral, we express the state of the light that diffracts from an
aperture to a point, by superposition of two or more waves. The amplitudes of the waves are …

Theoretical and experimental study of optical diffractometry based on Fresnel diffraction from a transmission phase step

Application of Fresnel diffraction from the edge of a transparent plate to measurement of glucose concentration

S Bahmanpour, A Mahmoudi - Applied Optics, 2021 - opg.optica.org
We present a new method for measuring the solution concentration based on laser light
diffraction from the edge of a glass plate immersed in the solution. It is shown experimentally …
