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…
Direct Schmidt number measurement of high-gain parametric down conversion
I. V. Dyakonov, P. R. Sharapova, T. Sh. Iskhakov +1
In this work we estimate the transverse Schmidt number for the bipartite bright squeezed vacuum state by means of second-order intensity correlation function measurement. Assuming…
Spatially single-mode source of bright squeezed vacuum
A. M. Pérez, T. Sh. Iskhakov, P. Sharapova +4
Bright squeezed vacuum, a macroscopic nonclassical state of light, can be obtained at the output of a strongly pumped non-seeded traveling-wave optical parametric amplifier (OPA).…
