TecnOPTO Home
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.
Our last paper in Optics Letters is entitled Shaped vector beams generated with a phase-only modulation—retarder optical configuration.
In this work we present a new configuration to generate vector beams, with shaped intensity and polarization distributions. The system is based on using on two liquid-crystal spatial light modulators (SLM). The first device is used in a scalar mode to shape an input linearly polarized beam with a phase-only computer-generated hologram. Then, the Fourier transform is optically formed onto the second SLM, which operates as a pixelated retarder to spatially modify the state of polarization. The proposed optical architecture allows shaping the amplitude profile,
while easily generating the cylindrically polarized vector beam pattern.
The work has been done in collaboration with Prof. Jeffrey A. Davis and Prof. Don M. Cottrell, from San Diego State University.
