Rubidium-Doped KTiOPO Waveguides as a Dual-Type Photon Pair Source
Patrick Hendra, Josué R. León-Torres, Valerio Flavio Gili +1
We investigate the dual generation of type-0 and type-II spontaneous parametric down conversions (SPDCs) within a single periodically poled rubidium-doped KTiOPO (PPRKTP) waveg…

Non-degenerate SPDC photon-pair source for UV-A illumination
Preetisha Goswami, Marta Gilaberte Basset, Jorge Fuenzalida +2
We present a frequency-correlated non-degenerate photon-pair source consisting of a second-order nonlinear crystal that generates ultraviolet UV-A and infrared light via spontaneou…

Benchmarking of Fluorescence Lifetime Measurements using Time-Frequency Correlated Photons
Tobias Bernd Gäbler, Nitish Jain, Patrick Then +3
The investigation of fluorescence lifetime became an important tool in biology and medical science. So far, established methods of fluorescence lifetime measurements require the il…
