60(11):3203-3210.
PMID: 33983220
Radially self-accelerating light exhibits an intensity pattern that describes a spiraling trajectory around the optical axis as the beam propagates. In this article, we show in simulation and experiment how...

. 2019 Nov;
27(22):31456-31464.
PMID: 31684380
Along with the growing interest in using the transverse-spatial modes of light in quantum and classical optics applications, developing an accurate and efficient measurement method has gained importance. Here, we...

Appl Opt
. 2016 May;
55(12):B14-9.
PMID: 27140120
We show that there are a number of ways to transform an arbitrary polarization state into another with just two quarter wave plates (QWPs). We have verified this geometrically using...

. 2015 Oct;
40(19):4516-9.
PMID: 26421570
Polarization of paraxial Airy beam solutions of Maxwell's equations and its evolution with propagation have been studied. We experimentally demonstrate the existence of the cross-polarization component of the Airy beam,...

Appl Opt
. 2015 Sep;
54(22):6690-3.
PMID: 26368081
We show, both theoretically and experimentally, that the propagation of optical vortices in free space can be analyzed by using the width [w(z)] of the host Gaussian beam and the...

Opt Lett
. 2014 Aug;
39(15):4364-7.
PMID: 25078178
We have experimentally generated higher order optical vortices and scattered them through a ground glass plate that results in speckle formation. Intensity autocorrelation measurements of speckles show that their size...

PMID: 24977368
We embed a pair of vortices with different topological charges in a Gaussian beam and study its evolution through an astigmatic optical system, a tilted lens. The propagation dynamics are...
