Properties of bright squeezed vacuum at increasing brightness
P. R. Sharapova, G. Frascella, M. Riabinin +6
Bright squeezed vacuum (BSV) is a non-classical macroscopic state of light, which can be generated through high-gain parametric down-conversion or four-wave mixing. Although BSV is…
Orbital angular momentum modes of high-gain parametric down-conversion
Lina Beltran, Gaetano Frascella, Angela M. Perez +6
Light beams with orbital angular momentum (OAM) are convenient carriers of quantum information. They can be also used for imparting rotational motion to particles and provide high…
Giant Narrowband Twin-Beam Generation along the Pump Energy Propagation
Angela M. Perez, Kirill Yu. Spasibko, Polina R. Sharapova +3
Walk-off effects, originating from the difference between the group and phase velocities, limit the efficiency of nonlinear optical interactions. While transverse walk-off can be e…
Schmidt modes in the angular spectrum of bright squeezed vacuum
Polina R. Sharapova, Angela M. Perez, Olga V. Tikhonova +1
We study the spatial properties of high-gain parametric down-conversion (PDC). From the Hamiltonian we find the Schmidt modes, apply the Bloch-Messiah reduction, and calculate anal…
Compensation of anisotropy effects in the generation of two-photon light
Andrea Cavanna, Angela M. Pérez, Felix Just +2
We analyse a method to compensate for anisotropy effects in the spatial distribution of parametric down-conversion (PDC) radiation in bulk crystals. In this method, a single nonlin…
