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…
Efficient separation of the orbital angular momentum eigenstates of light
Mohammad Mirhosseini, Mehul Malik, Zhimin Shi +1
Orbital angular momentum (OAM) of light is an attractive degree of freedom for funda- mentals studies in quantum mechanics. In addition, the discrete unbounded state-space of OAM h…
Direct Measurement of a 27-Dimensional Orbital-Angular-Momentum State Vector
Mehul Malik, Mohammad Mirhosseini, Martin P. J. Lavery +3
The measurement of a quantum state poses a unique challenge for experimentalists. Recently, the technique of "direct measurement" was proposed for characterizing a quantum state in…
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…
