Quantum scanning synthetic optical holography
Josué R. León-Torres, Byron Caiza, Nadia Baumann +7
Synthetic optical holography (SOH) introduced holographic reconstruction into scanning optical microscopy, enabling quantitative phase imaging with sequential acquisition and point…
Noise resilient real-time phase imaging via undetected light
Josué R. León-Torres, Patrick Hendra, Yugant Mukeshbhai Hadiyal +5
Quantum imaging with undetected light has recently emerged as a technique in which quantum correlations and nonlinear interferometry are combined to decouple illumination and detec…
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…
Mid-infrared quantum scanning microscopy via visible light beyond spatial correlations
Josué R. León-Torres, Vasile-Laurentiu Dosan, Marija M. ÄurÄiÄ +4
The mid-infrared (MIR) region of the electromagnetic spectrum spans from 2- to 25-, serving as a valuable tool for accessing rich chemical information. Functional gro…
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…
