Lattice-plasmon induced asymmetric transmission in two-dimensional chiral arrays
N. Apurv Chaitanya, M. A. Butt, O. Reshef +3
Asymmetric transmission - direction-selective control of electromagnetic transmission between two ports - is an important phenomenon typically exhibited by two-dimensional chiral s…
Single-pass, second harmonic generation of ultrafast, higher order vector vortex beams at blue
Ravi Kiran Saripalli, Anirban Ghosh, N. Apurv Chaitanya +1
We report a novel experimental scheme for single-pass second harmonic generation (SHG) of vector vortex beam in the blue. Using an ultrafast Ti:Sapphire laser of pulse width ~17 fs…
Direct transfer of classical non-separable state into hybrid entangled two photon state
M. V. Jabir, N. Apurv Chaitanya, Manoj Mathew +1
Hybrid entangled states, having entanglement between different degrees-of-freedom (DoF) of a particle pair, are of great interest for quantum information science and communication…
Hollow Gaussian beam generation through nonlinear interaction of photons with orbital-angular-momemtum
N. Apurv Chaitanya, M. V. Jabir, J. Banerji +1
Hollow Gaussian beams (HGB) are a special class of doughnut shaped beams that do not carry orbital angular momentum (OAM). Such beams have a wide range of applications in many fiel…
Generation of perfect vortex of variable size and its effect in angular spectrum of the down-converted photons
M. V. Jabir, N. Apurv Chaitanya, A. Aadhi +1
The perfect vortex is a new class of optical vortex beam having ring radius independent of its topological charge (order). One of the simplest techniques to generate such beams is…
Efficient nonlinear generation of high power, higher order, ultrafast "perfect" vortices in green
N. Apurv Chaitanya, M. V. Jabir, G. K. Samanta
We report on efficient nonlinear generation of ultrafast, higher order "perfect" vortices at the green wavelength. Based on Fourier transformation of the higher order Bessel-Gauss…
