Generation of heralded vector-polarized single photons in remotely controlled topological classes
Samuel Corona-Aquino, Zeferino Ibarra-Borja, Omar Calderón-Losada +6
We demonstrate an experimental protocol for the preparation and control of heralded single photons in inhomogeneously polarized states, such as Vector Vortex and Full Poincaré beam…
Experimental study on the effects of photon-pair temporal correlations in entangled two-photon absorption
Samuel Corona-Aquino, Omar Calderón-Losada, Mayte Y. Li-Gómez +5
Entangled two-photon absorption (ETPA) has recently become a topic of lively debate, mainly due to the apparent inconsistencies in the experimentally-reported ETPA cross sections o…
Towards third-order parametric down-conversion in optical fibers
Andrea Cavanna, Jonas Hammer, Cameron Okoth +8
Optical fibers have been considered an optimal platform for third-order parametric down-conversion since they can potentially overcome the weak third-order nonlinearity by their lo…
Joint Spectral Characterization of Photon-Pair Sources
Kevin Zielnicki, Karina Garay-Palmett, Daniel Cruz-Delgado +6
The ability to determine the joint spectral properties of photon pairs produced by the processes of spontaneous parametric downconversion (SPDC) and spontaneous four wave mixing (S…
Fiber-based photon-pair source capable of hybrid entanglement in frequency and transverse mode, controllably scalable to higher dimensions
D. Cruz-Delgado, R. Ramirez-Alarcon, E. Ortiz-Ricardo +5
We have designed and implemented a photon-pair source, based on the spontaneous four wave mixing (SFWM) process in a few-mode fiber, in a geometry which permits multiple, simultane…
Photon pair generation by intermodal spontaneous four wave mixing in birefringent, weakly guiding optical fibers
K. Garay-Palmett, D. Cruz-Delgado, F. Dominguez-Serna +5
We present a theoretical and experimental study of the generation of photon pairs through the process of spontaneous four wave mixing (SFWM) in a few-mode, birefringent fiber. Unde…
Classical to quantum transfer of optical vortices
Veronica Vicuna-Hernandez, Hector Cruz-Ramirez, Roberto Ramirez-Alarcon +1
We show that an optical vortex beam, implemented classically, can be transferred to the transverse amplitude of a heralded single photon. For this purpose we have relied on the pro…
Configurable spatio-temporal properties in a photon-pair source based on spontaneous four wave mixing with multiple transverse modes
Daniel Cruz-Delgado, Jorge Monroy-Ruz Angela M. Barragan, Erasto Ortiz-Ricardo +4
We present an experimental and theoretical study of photon pairs generated by spontaneous four wave mixing (SFWM), based on birefringent phasematching, in a fiber which supports mo…
Observation of non-diffracting behavior at the single-photon level
Hector Cruz-Ramirez, Roberto Ramirez-Alarcon, Francisco J. Morelos +3
We demonstrate the generation of non-diffracting heralded single photons, i.e. which are characterized by a single-photon transverse intensity distribution which remains essentiall…
Effects of crystal length on the angular spectrum of spontaneous parametric downconversion photon pairs
Roberto Ramirez-Alarcon, Hector Cruz-Ramirez, Alfred B. U'Ren
We present a theoretical and experimental analysis of the joint effects of the transverse electric field distribution and of the nonlinear crystal characteristics on the properties…
