Tunable optical parametric generator based on the pump spatial walk-off
Andrea Cavanna, Felix Just, Polina R. Sharapova +3
We suggest a novel optical parametric generator (OPG) in which one of the down-converted beams is spontaneously generated along the Poynting vector of the pump beam. In this config…
Heralded Source of Bright Multi-mode Mesoscopic Sub-Poissonian Light
Timur Sh. Iskhakov, Vladyslav C. Usenko, Ulrik L. Andersen +3
In a direct detection scheme we observed 7.8 dB of twin-beam squeezing for multi-mode two-color squeezed vacuum generated via parametric down conversion. Applying post-selection, w…
Experimental Demonstration of Negative-Valued Polarization Quasi-Probability Distribution
K. Yu. Spasibko, M. V. Chekhova, F. Ya. Khalili
Polarization quasiprobability distribution defined in the Stokes space shares many important properties with the Wigner function for the position and momentum. Most notably, they b…
Raman-free, noble-gas-filled PCF source for ultrafast, very bright twin-beam squeezed vacuum
Martin A. Finger, Timur Sh. Iskhakov, Nicolas Y. Joly +2
We report a novel source of twin beams based on modulational instability in high-pressure argon-filled hollow-core kagomé-style photonic-crystal fibre. The source is Raman-free and…
Nonlinear interferometer for tailoring the frequency spectrum of bright squeezed vacuum
T. Sh. Iskhakov, S. Lemieux, A. Perez +3
We propose a method for tailoring the frequency spectrum of bright squeezed vacuum by generating it in a nonlinear interferometer, consisting of two down-converting nonlinear cryst…
Projective filtering of a single spatial radiation eigenmode
A. M. Pérez, P. R. Sharapova, S. S. Straupe +4
Lossless filtering of a single coherent (Schmidt) mode from spatially multimode radiation is a problem crucial for optics in general and for quantum optics in particular. It become…
