Free-space communication through turbulence: a comparison of plane-wave and orbital-angular-momentum encodings
Mohammad Mirhosseini, Brandon Rodenburg, Mehul Malik +1
Free-space communication allows one to use spatial mode encoding, which is susceptible to the effects of diffraction and turbulence. Here, we discuss the optimum communication mode…
Integrated multi vector vortex beam generator
Sebastian A. Schulz, Taras Machula, Ebrahim Karimi +1
A novel method to generate and manipulate vector vortex beams in an integrated, ring resonator based geometry is proposed. We show numerically that a ring resonator, with an approp…
On the validity of the paraxial approximation for electron acceleration with radially polarized laser beams
Vincent Marceau, Charles Varin, Michel Piché
In the study of laser-driven electron acceleration, it has become customary to work within the framework of paraxial wave optics. Using an exact solution to the Helmholtz equation…
Simulating thick atmospheric turbulence in the lab with application to orbital angular momentum communication
Brandon Rodenburg, Mohammad Mirhosseini, Mehul Malik +6
We describe a procedure by which a long () optical path through atmospheric turbulence can be experimentally simulated in a controlled fashion and scaled do…
Reconstructing the Poynting vector skew angle and wave-front of optical vortex beams via two-channel moiré deflectometery
Mohammad Yeganeh, Saifollah Rasouli, Mohsen Dashti +3
A novel approach based on the two-channel moiré deflectometry has been used to measure both wave-front and transverse component of the Poynting vector of an optical vortex beam. Ge…
