High Purity OAM Entangled Photons from SPDC with Reduced Spatial Spectral Correlations
F. Crislane V. de Brito, Sylwia Kolenderska, Piotr Kolenderski
Entanglement generated by Spontaneous Parametric Down Conversion (SPDC) involves multiple, often mutually correlated degrees of freedom. These degrees of freedom are often treated…

Gouy phase of type-I SPDC-generated biphotons
F. C. V. de Brito, I. G. da Paz, Brigitte Hiller +2
We consider a double Gaussian approximation to describe the wavefunction of twin photons (also called a biphoton) created in a nonlinear crystal via a type-I spontaneous parametric…
