Simple experimental realization of optical Hilbert Hotel using scalar and vector fractional vortex beams
Subith Kumar, Anirban Ghosh, Chahat Kaushik +4
Historically, infinity was long considered a vague concept - boundless, endless, larger than the largest - without any quantifiable mathematical foundation. This view changed in th…
Quench dynamics of edge states in a finite extended Su-Schrieffer-Heeger system
Anirban Ghosh, Andy M. Martin, Sonjoy Majumder
We examine the quench dynamics of an extended Su-Schrieffer-Heeger(SSH) model involving long-range hopping that can hold multiple topological phases. Using winding number diagrams…
Bright entangled photon source without stringent crystal temperature and laser frequency stabilization
Sandeep Singh, Vimlesh Kumar, Anirban Ghosh +1
Entangled photon sources (EPS), the major building block for a variety of quantum communication protocols, are commonly developed by utilizing the spontaneous parametric down-conve…
Single-pass, nonlinear frequency conversion of full Poincaré beams
K. Subith, Ravi K. Saripalli, Anirban Ghosh +1
Full Poincaré (FP) beams, a special class of fully correlated beams generated through the coaxial superposition of a Laguerre-Gauss and fundamental Gaussian modes of orthogonal pol…
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…
Simultaneous generation of high power, ultrafast 1D and 2D Airy beams and their frequency doubling characteristics
Raghwinder S. Grewal, Anirban Ghosh, G. K. Samanta
We report on a simple experimental scheme based on a pair of cylindrical lenses (convex and concave) of same focal length and common optical elements producing high power optical b…
Controlled generation, manipulation and frequency conversion of broadband orbital angular momentum spectrum of asymmetric optical vortex beams
Sabir Ul Alam, A. Srinivasa Rao, Anirban Ghosh +2
We report on generation and control of tunable, broad orbital angular momentum (OAM) spectrum of a vortex beam. Using two spiral phase plates (SPPs), we have converted the Gaussian…
