TecnOPTO Home & Highlights
TecnOPTO (Grupo de Tecnologias Ópticas y Optoelectronicas) is the Group of Optics and Optoelectronic Technologies at University Miguel Hernández, in Elche, Spain.
Our group develops different research lines, all within the field of Physical Optics and Optolectronics. We are located at the University Miguel Hernández, in the beautiful city of Elche, in Spain.
We enjoy doing research and working in projects with collaborators all over the world. We also enjoy teaching and involving our students in our projects.
TecnOPTO at COS-SPIE Photonics Asia 2023
We have attended SPIE-COS Photonics Asia 2023 conference, held in Beijing in October 14-16th, 2023.
We have participated at the conference on Holography, Diffractive Optics, and Applications XIII.
Ignacio Moreno delivered the invited talk entitled Diffraction gratings with full amplitude, phase, and polarization control: physical realization on liquid-crystal spatial light modulators.
MarÃa del Mar Sánchez-López delivered the invited talk entitled Triplicator phase grating implementation in pixelated displays.
PhD student Shang Gao also attended the conference.
A great opportunity to meet in person the Chinese optical community.
Our new paper entitled Liquid crystal anisotropic axicon for the generation of non-diffracting Bessel beams with longitudinally varying polarization is now published in the journal Optics and Laser Technology.
In this work we demonstrate a tunable liquid–crystal element of linear phase profile along the radial coordinate. In combination with a regular refractive axicon, it behaves as an anisotropic axicon, generating the collinear superposition of two orthogonally polarized Bessel beams with different propagation constant. This superposition results in a Bessel beam where the state of polarization (SOP) varies periodically along propagation.
The work has been done with our collaborators at the Military University of Technology, Warsaw (Poland), Noureddine Bennis, Anna Spadlo and Tomasz Jankowski, together with José Francisco Algorri, from University of Cantabria, in Santander (Spain).
