Strategic Focus

Optics and Photonics Research Group (GOF) seeks to contribute to scientific knowledge on topics related to information digital and optical processing, coherence, holography, diffractive optics, optical metrology, visual optics, non-linear optics, and photonics. The GOF group will continue to be a leading group in areas such as optics and photonics nationally, and in the training of highly-trained scientific personnel. The group aims to maintain and strengthen its international future plans by means of agreements, academic exchanges, publications, and participation in congresses and courses.
