Free Space Continuous Variable Quantum Key Distribution with Discrete Phases
Anju Rani, Pooja Chandravanshi, Jayanth Ramakrishnan +6
Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authent…
Exploring the route from leaky Berreman modes to bound states in continuum
Ghanasyam Remesh, Pravin Vaity, Venu Gopal Achanta +1
We study coupling of leaky Berreman modes in polar dielectric films (SiO2) through a thin metallic layer (gold) and show the familiar signatures of normal mode splitting. Due to ve…
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…
Direct transfer of pump amplitude to parametric down-converted photons
Ali Anwar, Pravin Vaity, Chithrabhanu Perumangatt +1
We numerically and experimentally show that all photons generated by spontaneous parametric down-conversion (SPDC) follow a transverse amplitude similar to that of the pump. This a…
