Abstract
Parametric down-conversion is a second-order nonlinear process in which a pump photon breaks up into two separate photons known as the signal photon and the idler photon. Due to the phase-matching constraints, the signal and idler photons are rendered entangled in their: energy and emission-time, position and transverse momentum, and angular position and orbital angular momentum. Because of these correlations, the signal and idler photons can be described adequately only as a single, two-photon system. In this talk, I am going to present our studies on the coherence and entanglement properties of the down-converted two-photon field, through two-photon interference effects in temporal, spatial and angular domains.

Anand Kumar Jha is a PhD student in the research group of Prof. Robert W. Boyd at the Institute of Optics, University of Rochester, New York. He transferred there in 2003 from the Physics PhD program at the University of Illinois at Urbana-Champaign. He received the BSc and MSc in Physics in 2002 from the Indian Institute of Technology (IIT), Kharagpur, India. Anand also plays a mean game of badminton.
