Bi-photon propagation control with optimized wavefront by means of Adaptive Optics

M. Minozzi, S. Bonora, A. V. Sergienko +2

We present an efficient method to control the spatial modes of entangled photons produced through SPDC process. Bi-photon beam propagation is controlled by a deformable mirror, tha…

Object Identification Using Correlated Orbital Angular Momentum States

Nestor Uribe-Patarroyo, Andrew Fraine, David S. Simon +2

Using spontaneous parametric down conversion as a source of entangled photon pairs, correlations are measured between the orbital angular momentum (OAM) in a target beam (which con…

Two-Photon Spiral Imaging with Correlated Orbital Angular Momentum States

David S. Simon, Alexander V. Sergienko

The concept of correlated two-photon spiral imaging is introduced. We begin by analyzing the joint orbital angular momentum (OAM) spectrum of correlated photon pairs. The mutual in…
