Anisotropic Spatial Entanglement
Satyajeet Patil, Shashi Prabhakar, Ayan Biswas +2
The photon-pairs generated through spontaneous parametric down-conversion (SPDC) possess strong correlations in their transverse position and momentum degrees of freedom. For such…
Optical-vortex diagnostics via Fraunhofer slit diffraction with controllable wavefront curvature
A. Bekshaev, L. Mikhaylovskaya, S. Patil +2
Far-field slit-diffraction of circular optical-vortex (OV) beams is efficient for measurement of the topological charge (TC) magnitude but does not reveal its sign. We show that th…
Spatial distribution of Spontaneous Parametric Down-Converted Photons for higher order Optical Vortices
Shashi Prabhakar, Salla Gangi Reddy, A Aadhi +4
We make a source of entangled photons (SEP) using spontaneous parametric down-conversion (SPDC) in a non-linear crystal and study the spatial distribution of photon pairs obtained…
Propagation of an arbitrary vortex pair through an astigmatic optical system and determination of its net topological charge
Salla Gangi Reddy, Shashi Prabhakar, A Aadhi +2
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 dynam…
Experimental generation of ring-shaped beams with random sources
Salla Gangi Reddy, Ashok Kumar, Shashi Prabhakar +1
We have experimentally reproduced ring shaped beams from the scattered Laguerre-Gaussian and Bessel-Gaussian beams. A rotating ground glass plate is used as a scattering medium and…
