Journal ArticleDOI
Higher order optical vortices and formation of speckles
TL;DR: Higher order optical vortices are experimentally generated and scattered through a ground glass plate that results in speckle formation and intensity autocorrelation measurements of speckles show that their size decreases with an increase in the order of the vortex.
Journal ArticleDOI
Experimental generation of ring-shaped beams with random sources
TL;DR: This work experimentally reproduced ring-shaped beams from the scattered Laguerre-Gaussian and Bessel- Gaussian beams using a rotating ground glass plate and a plano-convex lens at the Fourier plane.
Journal ArticleDOI
Divergence of optical vortex beams.
Salla Gangi Reddy,Chithrabhanu Permangatt,Shashi Prabhakar,Ali Anwar,J. Banerji,Ravindra Pratap Singh +5 more
TL;DR: It is shown 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 inner and outer radii of the vortex beam at the source plane as defined in [Opt. Lett.39, 4364].
Journal ArticleDOI
Revealing the order of a vortex through its intensity record
TL;DR: The feasibility of an experimental technique for determining the order of optical vortices is demonstrated and the beauty of going to complementary spaces, which has been employed earlier also to find the information not available in other domains, is shown.
Journal ArticleDOI
Experimentally observed decay of high-dimensional entanglement through turbulence
Yingwen Zhang,Shashi Prabhakar,Shashi Prabhakar,Alpha Hamadou Ibrahim,Filippus S. Roux,Filippus S. Roux,Andrew Forbes,Thomas Konrad +7 more
TL;DR: In this article, the effects of turbulence on photonic states generated by spontaneous parametric down-conversion, both theoretically and experimentally, are investigated, using a single phase screen based on the Kolmogorov theory of turbulence.
