Experimental generation of an optical field with arbitrary spatial coherence properties
Brandon Rodenburg, Mohammad Mirhosseini, Omar S. Magaña-Loaiza +1
We describe an experimental technique to generate a quasi-monochromatic field with any arbitrary spatial coherence properties that can be described by the cross-spectral density fu…
Amplification of Angular Rotations Using Weak Measurements
Omar S. Magana-Loaiza, Mohammad Mirhosseini, Brandon Rodenburg +1
We present a weak measurement protocol that permits a sensitive estimation of angular rotations based on the concept of weak-value amplification. The shift in the state of a pointe…
Rapid Generation of Light Beams Carrying Orbital Angular Momentum
Mohammad Mirhosseini, Omar S. Magana-Loaiza, Changchen Chen +3
We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerr…
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…
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…
