TecnOPTO Home & Highlights

GrupoTecnOPTO (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.




A new paper is available at OSA Continuum entitled Encoding complex amplitude information onto phase-only diffractive optical elements using binary phase Nyquist gratings.

In this new work we reexamine a simple technique for encoding complex amplitude information onto a phase-only SLM. The approach uses a two-dimensional checkerboard binary phase diffraction grating where the diffraction efficiency is spatially varied.

We provide evidence of the usefulness of the technique but also about the limitations imposed by the current LCOS technology, which do not allow fully exploiting their high resolution, affected by the fringing effect.

The work has been done in collaboration with our coleagues at San Diego State University, Prof. Jeffrey A. Davis, Prof. Don M. Cottrell and Everett Wolfe.
