Frequency-correlation requirements on the biphoton wave function in an induced-coherence experiment between separate sources
Rojas Santana, Arturo; Jiménez Machado, Gerard; López Mago, Dorilian; Pérez Torres, Juan (American Physical Society, 2020-11-11)
Article
Accés obertThere is renewed interest in using the coherence between beams generated in separate down- converter sources for new applications in imaging, spectroscopy, microscopy and optical coherence tomography (OCT). These schemes ... -
How to automate a kinematic mount using a 3D printed arduino-based system
Salazar Serrano, Luis Jose; Jiménez Machado, Gerard; Pérez Torres, Juan (2018-06-01)
Article
Accés obertWe demonstrate a simple, flexible and cost-effective system to automatize most of the kinematic mounts available nowadays on the market. It combines 3D-printed components, an Arduino board, stepper motors and simple ... -
Knotting fractional-order knots with the polarization state of light
Pisanty, Emilio; Jiménez Machado, Gerard; Vicuña Hernández, Verónica; Picón, Antonio; Celi, Alessio; Pérez Torres, Juan; Lewenstein, Maciej (2019-08-01)
Article
Accés obertThe fundamental polarization singularities of monochromatic light are normally associated with invariance under coordinated rotations: symmetry operations that rotate the spatial dependence of an electromagnetic field by ... -
Measurement of noise-induced loss of polarization coherence
Jiménez Machado, Gerard (Universitat Politècnica de Catalunya, 2016-10)
Treball Final de Grau
Accés restringit per decisió de l'autorExperimental implementation of a Quantum-Optical Coherence Tomography (Q-OCT) system, by means of measuring and quantifying induced coherence. -
Optical coherence tomography with a nonlinear interferometer in the high parametric gain regime
Jiménez Machado, Gerard; Frascella, Gaetano; Pérez Torres, Juan; Chekhova, Maria (2020-08-31)
Article
Accés obertWe demonstrate optical coherence tomography based on an SU(1,1) nonlinear interferometer with high-gain parametric down-conversion. For imaging and sensing applications, this scheme promises to outperform previous experiments ... -
Optical sectioning in induced coherence tomography with frequency-entangled photons
Valles Marin, Adam; Jiménez Machado, Gerard; Salazar Serrano, Luis Jose; Pérez Torres, Juan (American Physical Society, 2018-02-14)
Article
Accés obertWe demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)]. This can be viewed as a different type of optical coherence ... -
Pendulum dynamics in an amusement park
Gurri Pérez, Pol; Amat, David; Espar Masip, Joan; Puig, Jordi; Jiménez Machado, Gerard; Sendra Molins, Lluc; Pardo Soto, Luis Carlos (2017-05-01)
Article
Accés obertPendulums have long been used to to determine the kinematics of non-inertial rotating systems. A proper study of this classical mechanical device under the action of a rotating reference frame can fully describe the behavior ... -
Quantum Coherence and Quantum Correlations
Jiménez Machado, Gerard (Universitat Politècnica de Catalunya, 2017-07-09)
Projecte Final de Màster Oficial
Accés obert
Realitzat a/amb: Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de BarcelonaWe demonstrate a new type of optical coherence tomography (OCT) scheme based on ideas put forward by Mandel's group in 1991, curiously the same year than the first OCT scheme was demonstrated. It involves the measurement ...
