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…
Photon triplets from integrated microrings: A path towards deterministic non-Gaussianity on a chip
Samuel E. Fontaine, J. E. Sipe, Marco Liscidini +1
We propose cascaded spontaneous four-wave mixing (SFWM) in microring resonators as a scalable and efficient approach for directly generating non-Gaussian states of light. Focusing…
Coherent control of photon pairs via quantum interference between second- and third-order quantum nonlinear processes
Alessia Stefano, Samuel E. Fontaine, J. E. Sipe +1
Genuine quantum interference between independent nonlinear processes of different order provides a route to coherent control that cannot be reduced to a classical field interferenc…
Non-Gaussian states via pump-depleted SPDC
Colin Vendromin, Samuel E. Fontaine, J. E. Sipe
We develop a model for non-Gaussian state generation via spontaneous parametric down-conversion (SPDC) in InGaP microring resonators. The nonlinear Hamiltonian is written in terms…
Photon pair generation via down-conversion in III-V semiconductor microrings: modal dispersion and quasi-phase matching
Samuel E. Fontaine, Colin Vendromin, Trevor J. Steiner +7
We explore how III-V semiconductor microring resonators can efficiently generate photon pairs and squeezed vacuum states via spontaneous parametric down-conversion by utilizing the…
