Hong-Ou-Mandel effect with two frequency-entangled photons of vastly different color
Felix Mann, Helen M. Chrzanowski, Marlon Placke +2
In the original formulation of the Hong-Ou-Mandel (HOM) experiment, when two otherwise indistinguishable photons are incident upon the two input ports of a balanced beam splitter,…

Noise analysis of a quasi-phase-matched quantum frequency converter and higher-order counter-propagating SPDC
Felix Mann, Helen M. Chrzanowski, Felipe Gewers +2
Quantum frequency conversion (QFC) will be an indispensable ingredient in future quantum technologies. For example, large-scale fibre-based quantum networks will require QFC to int…

Telecom-Band SPDC in AlGaAs-on-Insulator Waveguides
Marlon Placke, Jan Schlegel, Felix Mann +5
Widespread commercial adoption of telecom-band quantum-key-distribution (QKD) will require fully integrated, room-temperature transmitters. Implementing highly efficient spontaneou…
