Surface spontaneous parametric down-conversion [PDF]
Physical Review Letters, 2009 Surface spontaneous parametric down-conversion is predicted as a consequence of continuity requirements for electric- and magnetic-field amplitudes at a discontinuity of chi2 nonlinearity.

Angular Schmidt Modes in Spontaneous Parametric Down-Conversion [PDF]
Physical Review A, 2011 We report a proof-of-principle experiment demonstrating that appropriately chosen set of Hermite-Gaussian modes constitutes a Schmidt decomposition for transverse momentum states of biphotons generated in the process of spontaneous parametric down ...

Multimode Spontaneous Parametric Down-Conversion in the Lossy Medium [PDF]
Journal of Modern Optics, 2009 We study the process of multimode Spontaneous Parametric Down--Conversion (SPDC) in the lossy, one dimensional waveguide. We propose a description using first order Correlation Functions (CF) in the fluorescence fields, as a very fruitful and easy ...

Towards spontaneous parametric down conversion from monolayer MoS2. [PDF]
Sci Rep, 2018 AbstractWe present a detailed study of the second order nonlinearity of 2D (mono-atomic layer) dichalcogenide MoS2, both in the visible and in the IR regime, and test its potential for spontaneous parametric down-conversion (SPDC), the amplification of vacuum fluctuations mediated by optical nonlinearity.

Background and Review of Cavity-Enhanced Spontaneous Parametric Down-Conversion. [PDF]
J Res Natl Inst Stand Technol, 2019 Spontaneous parametric down-conversion (SPDC) in a nonlinear crystal has been a workhorse for the generation of entangled and correlated single-photon pairs used for quantum communications applications for nearly three decades.

Time Ordering in Spontaneous Parametric Down-conversion [PDF]
AIP Conference Proceedings, 2011 We consider the multi‐mode parametric down‐conversion Hamiltonian that governs the evolution of the fields inside a nonlinear crystal. If the Hamiltonian does not commute with itself at all times—as is the case for the multimode down‐conversion Hamiltonian—then the expansion of the evolution operator must take the form of the time‐ordered Dyson series,

Towards Measuring Terahertz Photon Statistics by a Superconducting Bolometer
Sensors, 2021 Statistical distributions of the analog readings of an antenna-coupled THz superconducting bolometer were measured and analyzed under a special type of irradiation by low-energy fluxes of THz photons with Poisson photon statistics and controllable mean ...
