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
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | Nature Publishing Group | 2016-09-20Laser traps provide contactless manipulation of plasmonic nanoparticles (NPs) boosting the development of numerous applications in science and technology. The known trapping configurations allow immobilizing and moving single NPs or assembling t[...]texto impreso

Rodrigo Martín-Romo, José Augusto ; Caravaca Aguirre, Antonio Miguel ; Alieva, Tatiana Krasheninnikova ; Cristóbal Pérez, Gabriel ; Calvo Padilla, María Luisa | The Optical Society Of America | 2011-03-14Three-dimensional microparticle movements induced by laser beams with a funnel- and tubular pod-like structure, in the neighbourhood of the focal plane of an optical trapping setup, are experimentally studied. The funnel and pod beams constructe[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Duadi, Hamootal ; Alieva, Tatiana Krasheninnikova ; Zalevsky, Zeev | The Optical Society Of America | 2010-01-18The gyrator transform is a useful tool for optical information processing applications. In this work we propose a multi-stage phase retrieval approach based on this operation as well as on the well-known Gerchberg-Saxton algorithm. It results in[...]texto impreso
Martínez Matos, Óscar ; Calvo Padilla, María Luisa ; Cheben, Pavel ; Rodrigo Martín-Romo, José Augusto ; Janz, Siegfried ; Xu, Dan-Xia ; Delâge, André | Elsevier Science BV | 2007-02-01We propose a new type of arrayed waveguide grating (AWG) multiplexer/demultiplexer based on modified group refractive index. This device is composed by an array of straight and parallel waveguides of equal length and each waveguide consist of tw[...]texto impreso
Martínez Matos, Óscar ; Cheben, Pavel ; Calvo Padilla, María Luisa ; Rodrigo Martín-Romo, José Augusto ; Monte Muñoz de la Peña, Francisco del | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2007We report recent results obtained with volume holographic gratings recorded in a new photopolymerisable glass modified with high refractive index species at molecular level. Various not previously observed performances have been achieved for dif[...]texto impreso
Cámara, Alejandro ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | The Optical Society Of America | 2013-06-03Partially coherent light provides attractive benefits in imaging, beam shaping, free-space communications, random medium monitoring, among other applications. However, the experimental characterization of the spatial coherence is a difficult pro[...]texto impreso
Soto Rueda, Juan Manuel ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | Optical Society of America | 2018-01-01Quantitative label-free imaging is an important tool for the study of living microorganisms that, during the last decade, has attracted wide attention from the optical community. Optical diffraction tomography (ODT) is probably the most relevant[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | Optical Society of America | 2006-10On the basis of a matrix formalism, we analyze the paraxial optical systems composed by generalized lenses and fixed free-space intervals, suitable for orthosymplectic transformations in phase space. Flexible configurations to perform the attrac[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2011The application of partially coherent optical beams for imaging, free space communication, random medium analysis requires controlling its mutual intensity. This task can be done using the phase-space tomography method consisting on the reconstr[...]texto impreso
Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Cámara, A. ; Abramochkin, E. | Optical Society of America | 2013-11-01Stable and spiral coherent beams, which do not change the form of their intensity distribution apart from possible scaling and rotation during propagation and therefore possess self-healing properties, are widely applied in science and technolog[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | Optical Society of America | 2009-06We propose a simple approach for the phase space tomography reconstruction of the Wigner distribution of paraxial optical beams separable in Cartesian coordinates. It is based on the measurements of the antisymmetric fractional Fourier transform[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | The Optical Society Of America | 2011-07-11We show the adaptation of a multifunctional optical system consisting of two spatial light modulators for the optimal measurement of the Radon-Wigner transform of one-dimensional signals. The proposed Radon-Wigner display allows reconstructing t[...]texto impreso
