Experimental reconstruction of spatial Schmidt modes for a wide-field SU(1,1) interferometer
Gaetano Frascella, Roman V. Zakharov, Olga V. Tikhonova +1
We study the spatial mode content at the output of a wide-field SU(1,1) interferometer, i.e. a nonlinear interferometer comprising two coherently-pumped spatially-multimode optical…

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…

Wide-field SU(1,1) interferometer
G. Frascella, E. E. Mikhailov, N. Takanashi +3
An interferometer uses a sequence of two optical parametric amplifiers for achieving sub-shot-noise sensitivity to a phase shift introduced in between. We present t…
