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…

Limitations of Entangled Two-Photon Absorption detection

René Pollmann, Franz Roeder, Christine Silberhorn +1

We introduce a method for determining the sensitivity of any given Entangled Two-Photon Absorption (ETPA) measurement. By modeling all signal and noise contributions to the measure…

Towards integrated sensors for optimized OCT with undetected photons

Franz Roeder, René Pollmann, Viktor Quiring +3

The development of practical sensors for optical coherence tomography (OCT) with undetected photons requires miniaturization via integration. To be practical, these sensors must ex…

A ultrabright, two-colour photon pair source based on thin-film lithium niobate for bridging visible and telecom wavelengths

Silia Babel, Laura Bollmers, Franz Roeder +9

We present the design and characterisation of a guided-wave, bright and highly frequency non-degenerate parametric down-conversion source in thin-film lithium niobate. The source g…

Ultra-broadband non-degenerate guided-wave bi-photon source in the near and mid-infrared

Franz Roeder, Abira Gnanavel, René Pollmann +6

The latest applications in ultrafast quantum metrology require bright, broadband bi-photon sources with one of the photons in the mid-infrared and the other in the visible to near…

Bounding elastic photon-photon scattering at MeV using a laser-plasma platform

R. Watt, B. Kettle, E. Gerstmayr +36

We report on a direct search for elastic photon-photon scattering using x-ray and photons from a laser-plasma based experiment. A gamma photon beam produced by a laser wakefiel…

Integrated, bright, broadband parametric down-conversion source for quantum metrology and spectroscopy

René Pollmann, Franz Roeder, Victor Quiring +4

Broadband quantum light is a vital resource for quantum metrology and spectroscopy applications such as quantum optical coherence tomography or entangled two photon absorption. For…

Measurement of ultrashort bi-photon correlation times with an integrated two-colour broadband SU(1,1)-interferometer

F. Roeder, R. Pollmann, M. Stefszky +7

The bi-photon correlation time, a measure for the conditional uncertainty in the temporal arrival of two photons from a photon pair source, is a key performance identifier for many…

A laser-plasma platform for photon-photon physics

B. Kettle, D. Hollatz, E. Gerstmayr +35

We describe a laser-plasma platform for photon-photon collision experiments to measure fundamental quantum electrodynamic processes such as the linear Breit-Wheeler process with re…
