Spectral and statistical properties of high-gain parametric down-conversion
Kirill Spasibko
Parametric down-conversion (PDC) is mostly known in the low-gain (spontaneous) regime, in which the correlated photon pairs are produced. Spontaneous PDC (SPDC) plays a very import…
Measurement of coupled spatiotemporal coherence of parametric down-conversion under negative group velocity dispersion
Paula Cutipa, Kirill Yu. Spasibko, Maria V. Chekhova
We present a direct measurement of the spatiotemporal coherence of parametric down-conversion in the range of negative group-velocity dispersion. In this case, the frequency-angula…
Study of broadband multimode light via non-phase-matched sum frequency generation
Denis A. Kopylov, Kirill Yu. Spasibko, Tatiana V. Murzina +1
We propose non-phase-matched sum frequency generation (SFG) as a method for characterizing broadband multimode light. We demonstrate its advantages using high-gain parametric down…
Indefinite-mean Pareto photon distribution from amplified quantum noise
Mathieu Manceau, Kirill Yu. Spasibko, Gerd Leuchs +2
Extreme events appear in many physics phenomena, whenever the probability distribution has a ''heavy tail'', differing very much from the equilibrium one. Most unusual are the case…
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…
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…
