Comparison of coherence area measurement techniques for bright entangled twin beams
Ashok Kumar, Hayden Nunley, Alberto M. Marino
Quantum states of light with multiple spatial modes are fundamental for quantum imaging and parallel quantum information processing. Thus, their characterization, which can be achi…
Observation of Spatial Quantum Correlations in the Macroscopic Regime
Ashok Kumar, Hayden Nunley, A. M. Marino
Spatial quantum correlations in the transverse degree of freedom promise to enhance optical resolution, image detection, and quantum communications through parallel quantum informa…
Higher order optical vortices and formation of speckles
Salla Gangi Reddy, Shashi Prabhakar, Ashok Kumar +2
We have experimentally generated higher order optical vortices and scattered them through a ground glass plate that results in speckle formation. Intensity autocorrelation measurem…
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…
Measuring Mueller matrix of an arbitrary optical element with a fixed set of polarization optics
Salla Gangi Reddy, Shashi Prabhakar, A. Aadhi +4
We have described a novel way to determine the Mueller matrix of any optical element by using projection method. For this purpose, we have used two universal SU(2) gadgets for pola…
