Coincidence-based spectral engineering for spectral matching in cascaded downconversion
Mohammed Charafi, Alexandre Z. Leger, Samridhi Gambhir +1
Three-photon states generated via cascaded spontaneous parametric downconversion provide a direct route to multipartite entanglement. However, current implementations require caref…

Joint spectral characterization of SPDC photon pairs near 2 m in (Al)GaAs-on-insulator waveguides
Alexandre Z. Leger, Emil Z. Ulsig, Samuel E. Fontaine +8
Integrated photon-pair sources are a core component of chip-based quantum computing, communication, and metrology. Although such sources have been demonstrated at conventional tele…
