Parametric processes in nonlinear structures with reflections: an asymptotic-field approach

Tadeu Tassis, Salvador Poveda-Hospital, Nicolás Quesada +1

The generation of engineered quantum states of light via nonlinear processes is fundamental for quantum technologies based on photons. Although embedding nonlinear materials within…

High-gain effects in broadband continuous-wave parametric down conversion sources and measurements with undetected photons

Martin Houde, Franz Roeder, Christine Silberhorn +2

We study theoretically how high-gain effects affect the measurement outcome of visible signal spectra in undetected photon measurement schemes. We consider two interferometric conf…

Quantum Fisher information analysis for absorption measurements with undetected photons

Martin Houde, Franz Roeder, Christine Silberhorn +2

We theoretically compare the quantum Fisher information (QFI) for three configurations of absorption spectroscopy with undetected idler photons: an SU(1,1) interferometer with inte…

Ultrashort-pulse-pumped, single-mode type-0 squeezers in lithium niobate nanophotonics

Martin Houde, Liam Beaudoin, Robert Kwolek +3

We present design principles for ultrashort-pulse, type-0 phase-matched optical parametric amplifiers to generate and measure spectrally pure degenerate squeezed light. We consider…

Parametric processes in nonlinear structures with reflections: a transfer matrix method approach

Salvador Poveda-Hospital, Tadeu Tassis, Yves-Alain Peter +2

The Transfer Matrix Method is a powerful numerical tool for simulating wave propagation in layered media. It has been widely applied in many fields, although its use is typically r…
