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…

Mid-infrared quantum scanning microscopy via visible light beyond spatial correlations

Josué R. León-Torres, Vasile-Laurentiu Dosan, Marija M. Ćurčić +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…

Off-axis holographic imaging with undetected light

Josué R. León-Torres, Filip Krajinić, Mohit Kumar +5

Quantum imaging with undetected light (QIUL) can retrieve amplitude and phase information of an object by exploiting the quantum correlations of photon-pairs generated through spon…
