Alieva, Tatiana Krasheninnikova ; Abramochkin, Eugeny ; Asenjo García, Ana ; Razueva, Evgeniya | The Optical Society Of America | 2010-02-15Based on the ray transformation matrix formalism, we propose a simple method for generation of paraxial beams performing anisotropic rotation in the phase space during their propagation through isotropic optical systems. The widely discussed spi[...]texto impreso
Hermite-Gauss and Laguerre-Gauss modes of a continuous optical field in two dimensions can be obtained from each other through paraxial optical setups that produce rotations in (four-dimensional) phase space. These transformations build the SU(2[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Abramochkin, Eugeny ; Castro, Izan | The Optical Society Of America | 2013-09-09We present a method for efficient and versatile generation of beams whose intensity and phase are prescribed along arbitrary 3D curves. It comprises a non-iterative beam shaping technique that does not require solving inversion problems of light[...]texto impreso
Based on the analysis of second-order moments, a generalized canonical representation of a two-dimensional optical signal is proposed, which is associated with the angular Poincare sphere. Vortex-free ( or zero-twist) optical beams arise on the [...]texto impreso
Alieva, Tatiana Krasheninnikova ; Cámara, Alejandro ; Rodrigo Martín-Romo, José Augusto | Society of Photo-optical Instrumentation Engineers | 2015-03-13Partially coherent light provides attractive benefits for different applications in microscopy, astronomy, telecommunications, optical lithography, etc. However, design and generation of partially coherent beams with desirable properties is chal[...]texto impreso
On the basis of the modified Iwasawa decomposition of a lossless first-order optical system as a cascade of a lens, a magnifier, and a so-called orthosymplectic system, we show how to synthesize an arbitrary ABCD system (with two transverse coor[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Angulo Curto, María de las Mercedes ; Alieva, Tatiana Krasheninnikova | Springer Nature | 2020-10-27Optofluidics: Light forces for controlling heat nanosources and fluid flows New opportunities for controlling the motion of laser-heated gold nanoparticles and the associated convection currents in the surrounding fluid are achieved by using tai[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | The Electromagnetics Academy | 2010The numerical demonstration of the phase-space tomographic reconstruction method of non-separable beams is presented in this contribution. The Wigner distribution of a Laguerre-Gaussian beam is recovered from numerically simulated intensity meas[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | Nature Publishing Group | 2018-05-16A scalar polymorphic beam is designed with independent control of its intensity and phase along a strongly focused laser curve of arbitrary shape. This kind of beam has been found crucial in the creation of freestyle laser traps able to confine [...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Cristóbal Pérez, Gabriel ; Calvo Padilla, María Luisa | The Optical Society Of America | 2011-09-12We present a fast and robust non-interferomentric wavefield retrieval approach suitable for imaging of both amplitude and phase distributions of scalar coherent beams. It is based on the diversity of the intensity measurements obtained under con[...]texto impreso
It is shown how all global Wigner distribution moments of arbitrary order can be measured as intensity moments in the output plane of an appropriate number of separable first-order optical systems (generally anamorphic ones). The minimum number [...]
