Broadband bright twin beams and their up-conversion
Maria V. Chekhova, Semen Germanskiy, Dmitri B. Horoshko +5
We report on the observation of broadband (40 THz) bright twin beams through high-gain parametric down-conversion in an aperiodically poled lithium niobate crystal. The output phot…
Quantum tomography enhanced through parametric amplification
E. Knyazev, K. Yu. Spasibko, M. V. Chekhova +1
Quantum tomography is the standard method of reconstructing the Wigner function of quantum states of light by means of balanced homodyne detection. The reconstruction quality stron…
Detection loss tolerant supersensitive phase measurement with an SU(1,1) interferometer
Mathieu Manceau, Gerd Leuchs, Farid Khalili +1
In an unseeded SU(1,1) interferometer composed of two cascaded degenerate parametric amplifiers, with direct detection at the output, we demonstrate a phase sensitivity overcoming…
Multiphoton Effects Enhanced Due to Ultrafast Photon-Number Fluctuations
Kirill Yu. Spasibko, Denis A. Kopylov, Victor L. Krutyanskiy +3
Multi-photon processes are the essence of nonlinear optics. Optical harmonics generation and multi-photon absorption, ionization, polymerization or spectroscopy are widely used in…
