Abstract

Our group has been studying the optical parametric oscillator (OPO) as a source of entangled quantum states of light beams. A natural application for these entangled states is the realization of quantum communication. We started last year a collaboration with the group led by Prof. Michal Lipson of Cornell University, a pioneer in the area of nanophotonics with silicon chips, demonstrating possibilities for ultrafast modulation, confinement of light in very small volumes, and nonlinear optics on chips. In particular, the Cornell group demonstrated the operation of an OPO on a silicon chip. This project aims to study quantum properties of light in OPOs on silicon chips, enabling the use of very efficient classical information systems in quantum information protocols. (AU)
