Quantum-secured imaging
Mehul Malik, Omar S. Magaña-Loaiza, Robert W. Boyd
We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability all…
Measurement of the Orbital Angular Momentum Spectrum of Partially Coherent Fields using Double Angular Slit Interference
Mehul Malik, Sangeeta Murugkar, Jonathan Leach +1
We implement an interferometric method using two angular slits to measure the orbital angular momentum (OAM) mode spectrum of a partially coherent field. As the angular separation…
Near-Perfect Sorting of Orbital Angular Momentum and Angular Position States of Light
Malcolm N. O'Sullivan, Mohammad Mirhosseini, Mehul Malik +1
We present a novel method for efficient sorting of photons prepared in states of orbital angular momentum (OAM) and angular position (ANG). A log-polar optical transform is used in…
Influence of atmospheric turbulence on states of light carrying orbital angular momentum
Brandon Rodenburg, Martin P. J. Lavery, Mehul Malik +5
We have experimentally studied the degradation of mode purity for light beams carrying orbital angular momentum (OAM) propagating through simulated atmospheric turbulence. The turb…
Influence of Atmospheric Turbulence on Optical Communications using Orbital Angular Momentum for Encoding
Mehul Malik, Malcolm O'Sullivan, Brandon Rodenburg +5
We describe an experimental implementation of a free-space 11-dimensional communication system using orbital angular momentum (OAM) modes. This system has a maximum measured OAM ch…
