Selective tuning of Hilbert spaces in states encoded with spatial modes of light
Ali Anwar, Nijil Lal, Shashi Prabhakar +1
Spatial modes of light directly give the most easily accessible degree of freedom that span an infinite dimensional Hilbert space. The higher dimensional spatial mode entanglement…
Observing sub-Poissonian statistics of twisted single photons using oscilloscope
Nijil Lal, Biveen Shajilal, Ali Anwar +2
Heralded single photon sources (HSPS) from spontaneous parametric down-conversion are widely used as single photon sources. We study the photon number statistics of an HSPS carryin…
Single photon sources with different spatial modes
Nijil Lal, Anindya Banerji, Ayan Biswas +2
We study the correlation properties of single photons carrying orbital angular momentum (OAM) in a Hanbury Brown and Twiss (HBT) type experiment. We have characterized single photo…
Engineering of orbital angular momentum spectrum of down-converted photons with mode-invariant pump
Anindya Banerji, Ali Anwar, Hrushikesh Sable +2
In this article we investigate the orbital angular momentum spectrum of photons produced in parametric down conversion process. We study how the transverse profile of the pump mode…
