From quantum pulse gate to quantum pulse shaper -- enigneered frequency conversion in nonlinear optical waveguides
Benjamin Brecht, Andreas Eckstein, Andreas Christ +2
Full control over the spatio-temporal structure of quantum states of light is an important goal in quantum optics, to generate for instance single-mode quantum pulses or to encode…
Probing multimode squeezing with correlation functions
Andreas Christ, Kaisa Laiho, Andreas Eckstein +2
Broadband multimode squeezers constitute a powerful quantum resource with promising potential for different applications in quantum information technologies such as information cod…
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…
