Seeded SU(1,1) interferometry for Fourier-domain optical coherence tomography
Alejandra A. Padilla, Valentina Gacha, Daniel F. Urrego +1
We demonstrate Fourier-domain optical coherence tomography (FD-OCT) based on a seeded SU(1,1) interferometer. Multilayer objects are probed with broadband light centered at 1550nm,…
Constant sensitivity birefringence metrology using vector vortex beams
Gabriela Flores-Cova, Daniel Salamanca-Roldán, Carmelo Rosales-Guzmán +2
Differential Interference Contrast (DIC) microscopy and chiral analysis are two imaging techniques that measure the birefringence, i.e., the phase difference introduced by a sample…
Non-mechanical steering of the optical beam in spectral-domain Optical Coherence Tomography
Daniel F. Urrego, Gerard J. Machado, Juan P. Torres
We demonstrate in a {\it proof-of-concept} experiment spectral-domain optical coherence tomography where steering of the optical beam that probes the sample in a transverse scan do…
Quantum-inspired protocol for measuring the degree of similarity between spatial shapes
Daniel F. Urrego, Juan P. Torres
We put forward and demonstrate experimentally a {\it quantum-inspired} protocol that allows to quantify the degree of similarity between two spatial shapes embedded in two optical…
A quantum-inspired Fredkin gate based on spatial modes of light
Daniel F. Urrego, Dorilian Lopez-Mago, Verónica Vicuña-Hernández +1
Distinguishing between strings of data or waveforms is at the core of multiple applications in information technologies. In a quantum language the task is to design protocols to di…
Implementation and characterization of a controllable dephasing channel based on coupling polarization and spatial degrees of freedom of light
Daniel F. Urrego, Juan-Rafael Álvarez, Omar Calderón-Losada +3
We present the experimental implementation and theoretical model of a controllable dephasing quantum channel using photonic systems. The channel is implemented by coupling the pola…
