, 2013 We investigate the spontaneous parametric down-conversion (SPDC) process in biaxial nonlinear crystal BiB3O6 (BIBO) with a broadband pump. Under the type I and type II phase-matching conditions, we numerically calculate the influencing factors on SPDC ...

Optical Potts machine through networks of three-photon down-conversion oscillators
Nanophotonics, 2020 In recent years, there has been a growing interest in optical simulation of lattice spin models for applications in unconventional computing. Here, we propose optical implementation of a three-state Potts spin model by using networks of coupled ...

, 2018 The realization of efficient and miniature source of entangled photon pairs stills remains a challenge. In this work, we experimentally studied the possibility to enhance the process of spontaneous parametric down-conversion by surface plasmon polaritons.

Atom-mediated spontaneous parametric down-conversion in periodic waveguides [PDF]
Optics Letters, 2017 We propose the concept of atom-mediated spontaneous parametric down-conversion, in which photon-pair generation can take place only in the presence of a single two-level emitter, relying on the bandgap evanescent modes of a nonlinear periodic waveguide.

Local Realistic Interpretation of Entangled Photon Pairs in the Weyl-Wigner Formalism
Frontiers in Physics, 2020 A polarization correlation experiment with two maximally entangled photons created by spontaneous parametric down-conversion is studied in the Weyl-Wigner formalism, that reproduces the quantum predictions.

Heralded amplification of nonlocality via entanglement swapping
New Journal of Physics, 2020 To observe the loophole-free violation of the Clauser–Horne–Shimony–Holt (CHSH) inequality between distant two parties, i.e. the CHSH value $S\gt 2$ , the main limitation of distance stems from the loss in the transmission channel.

Photonic circuits for generating modal, spectral, and polarization entanglement [PDF]
, 2010 We consider the design of photonic circuits that make use of Ti:LiNbO(3) diffused channel waveguides to generate photons with various combinations of modal, spectral, and polarization entanglement.

Spontaneous parametric down-conversion in chirped, aperiodically-poled crystals [PDF]
International Journal of Quantum Information, 2015 We present a theoretical analysis of the process of spontaneous parametric down conversion (SPDC) in a nonlinear crystal characterized by a linearly-chirped χ(2) grating along the direction of propagation. Our analysis leads to an expression for the joint spectral amplitude, based on which we can derive various spectral–temporal properties of the ...
