Diffractive Optics: Research Groups

Introduction


The INAOE Diffractive Optics Group began in the 90’s as the Image Sciences Group. One of the most important activities developed during this period was the creation of conventional optic holograms and binary synthetic holograms through photographic techniques.


In 1998, under direction of Ph.D. Victor Arrizon Peña, the new Diffractive Optics Lab has focused on developing diffractive optic elements and synthetic phase holograms, set up with coherent light spatial modulators, -based on liquid crystal devices/mechanisms- that are electronically controlled.
Currently, for these tasks, there are six liquid crystal modulators (pneumatic type) of various formats and pixel count. In three of these liquid crystal modulators, molecules have induced azimuth rotation and are parallel-aligned.


Researcher
Ph.D. Victor Manuel Arrizón Peña is in charge of the Diffractive Optics Group, which is an open group because it is not formed by collaborators that work exclusively and solely for it. INAOE researchers that collaborate with this group are: Ph.D. Albertina Castro, Ph.D. David Sanchez de la Llave, Ph.D. Sabino Chávez-Cerda, Ph.D. Ruben Ramos Garcia and Ph.D. Hector Moya Cessa.


External Collaborations
The Diffractive Optics Group collaborates with researchers from other institutions, among them; Ph.D. Karen Volke (UNAM Physics Institute), Ph.D. Gustavo Rodriguez Zurita (BUAP, Physics, Math and Sciences Faculty), Ph.D. Luis Alfredo González (DIFUS, Sonora University.) and Ph.D. Alejandro Apolinar (Physics Dep. of Sonora University).


Doctorate Students: Rosibel Carrada, Ulises Ruiz and Maria Luisa Cruz.


Lines of Research of the Group
Its main activities include, development of different configurations that allow use of liquid crystal devices such as phase and quasiphase modulators. Other important research projects are: the development of synthetic holography codes that permit the formation of complex-arbitrary optic fields through the use of pure phase modulation functions.
Among the main applications: the formation of spatially structured fields for making multiple optical tweezers and for optical potential distributions for microparticle systems manipulation.
Recently, synthetic holograms are being applied in the development of multiple complex beams, in order to study their interaction in various nonlinear settings. Also, nondiffractive periodical and quasiperiodical fields have been produced for optical guide formation in holographic and photorefractive materials.
