Low random duty-cycle errors in periodically-poled KTP revealed by sum-frequency generation

Felix Mann, Helen M. Chrzanowski, Sven Ramelow

Low-noise quantum frequency conversion in periodically-poled nonlinear crystals has proved challenging when the pump wavelength is shorter than the target wavelength. This is - at…

Engineering AlGaAs-on-insulator towards quantum optical applications

Marlon Placke, Sven Ramelow

Aluminum gallium arsenide has highly desirable properties for integrated parametric optical interactions: large material nonlinearities, maturely established nanoscopic structuring…

Frequency-domain optical coherence tomography with undetected mid-infrared photons

Aron Vanselow, Paul Kaufmann, Ivan Zorin +3

Mid-infrared light scatters much less than shorter wavelengths, allowing greatly enhanced penetration depths for optical imaging techniques such as optical coherence tomography (OC…

Microscopy with undetected photons in the mid-infrared

Inna Kviatkovsky, Helen M. Chrzanowski, Ellen G. Avery +2

Owing to its capacity for unique (bio)-chemical specificity, microscopy withmid-IR illumination holds tremendous promise for a wide range of biomedical and industrial applications.…

An efficient, tunable, and robust source of narrow-band photon pairs at the Rb D1 line

Roberto Mottola, Gianni Buser, Chris Müller +6

We present an efficient and robust source of photons at the Rb D1-line (795 nm) with a narrow bandwidth of MHz. The source is based on non-degenerate, cavity-enha…

Ultra-broadband SPDC for spectrally far separated photon pairs

Aron Vanselow, Paul Kaufmann, Helen M. Chrzanowski +1

Generating photon pairs via spontaneous parametric down-conversion (SPDC) in nonlinear crystals is important for a wide range of quantum optics experiments with spectral properties…
