Spatial properties of entangled photon pairs generated in nonlinear layered structures
Jan Perina
A spatial quantum model of spontaneous parametric down-conversion in nonlinear layered structures is developed expanding the interacting vectorial fields into monochromatic plane w…
Evolution of Fock states in three mixed harmonic oscillators: quantum statistics
Faisal A. A. El-Orany, J. Perina, M. Sebawe Abdalla
In this communication we investigate the quantum statistics of three harmonic oscillators mutually interacting with each other considering the modes are initially in Fock states. A…
Generation of squeezed light in a nonlinear asymmetric directional coupler
Faisal A. A. El-Orany, J. Perina, M. Sebawe Abdalla
We show that a nonlinear asymmetric directional coupler composed of a linear waveguide and a nonlinear waveguide operating by nondegenerate parametric amplification is an effective…
Phase properties of the superposition of squeezed and displaced number states
Faisal A. A. El-Orany, J. Perina, M. Sebawe Abdalla
We show that a nonlinear asymmetric directional coupler composed of a linear waveguide and a nonlinear waveguide operating by nondegenerate parametric amplification is an effective…
Photon-number entangled states generated in Kerr media with optical parametric pumping
Anna Kowalewska-Kudłaszyk, Wiesław Leoński, Jan Peřina
Two nonlinear Kerr oscillators mutually coupled by parametric pumping are studied as a source of states entangled in photon numbers. Temporal evolution of entanglement quantified b…
