Spatial modes in waveguided parametric down-conversion
Andreas Christ, Kaisa Laiho, Andreas Eckstein +3
The propagation of several spatial modes has a significant impact on the structure of the emission from parametric down-conversion in a nonlinear waveguide. This manifests itself n…

Pure single photon generation by type-I PDC with backward-wave amplification
A. Christ, A. Eckstein, P. J. Mosley +1
We explore a promising method of generating pure heralded single photons. Our approach is based on parametric downconversion in a periodically-poled waveguide. However, unlike conv…
