Polarization coverage and self-healing characteristics of Poincaré-Bessel beam
Subith Kumar, Anupam Pal, Arash Shiri +2
As a vector version of scalar Bessel beams, Poincaré-Bessel beams (PBBs) have attracted a great deal of attention due to the presence of polarization singularities and their nondif…
Near-video frame rate quantum sensing using Hong-Ou-Mandel interferometry
Sandeep Singh, Vimlesh Kumar, Varun Sharma +2
Hong-Ou-Mandel (HOM) interference, the bunching of two indistinguishable photons on a balanced beam-splitter, has emerged as a promising tool for quantum sensing. There is a need f…
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…
