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. 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…
Off-axis holographic imaging with undetected light
Josué R. León-Torres, Filip KrajiniÄ, 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…
