We derive a comprehensive closed-form expression for the evolution of themutual intensity (MI) ofHermite -Laguerre Gaussian Schell-model beams (HLG-SMBs) during propagation through rotationally symmetric optical systems. We demonstrate that the [...]texto impreso
Highly collimated beams are required in numerous applications and techniques. Different methods have been proposed for collimating monochromatic point light sources during the recent years. In this work, we analyze how a finite size and polychro[...]texto impreso
Canhota, Miguel ; Silva, Francisco ; Weigand Talavera, Rosa María ; Crespo, Helder M. | Optical Soc Amer | 2017-08-01We present an implementation of dispersion-scan based on self-diffraction (SD d-scan) and apply it to the measurement of over octave-spanning sub-4-fs pulses. The results are compared with second-harmonic generation (SHG) d-scan. The efficiency [...]texto impreso
Soto Rueda, Juan Manuel ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | Optical Soc Amer | 2017-07-10Crucial benefits provided by partially coherent light microscopy such as improved spatial resolution, optical sectioning and speckle-noise suppression are exploited here to achieve 3D quantitative imaging: reconstruction of the object refractive[...]texto impreso
Santarsiero, Massimo ; Martínez Herrero, Rosario ; Maluenda, David ; González de Sande, J.C. ; Piquero Sanz, Gemma María ; Gori, F. | Optical Soc Amer | 2017-04-15A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence ca[...]texto impreso
Gálvez Alonso, Fernando ; Valle Granda, Javier del ; Gómez, A. ; Osorio, M. R. ; Granados, D. ; Pérez de Lara, D. ; Garcia, M.A. ; Vicent López, José Luis | Optical Soc Amer | 2016-10-01We have designed and fabricated a nanodevice exhibiting simultaneously ferromagnetic properties of nanostructures with plasmonic properties of continuous films. Our device consists of an array of nanomagnets on top of a continuous plasmonic film[...]texto impreso
Quantum metrology allows for a tremendous boost in the accuracy of measurement of diverse physical parameters. The estimation of a rotation constitutes a remarkable example of this quantum-enhanced precision. The recently introduced Kings of Qua[...]
