"I remember a few years ago a research colleague of mine saying with some indignation that the authors of scientific papers should receive royalties when they transfer copyrights to the publishers. The rationale behind it was simple...", Alípio Jorge

"There are features that unite us, both Portuguese and Brazilian, and that are bigger than the language. And those are apparent in our way of being and in the way we live, in the refusal to live regulatory shapes and procedures that castrate the spontaneous.", José Celso Freire Júnior

PhD student from UOSE wins Student Award

PhD student from UOSE wins Student Award

Luís Fernandes, researcher at the Optoelectronics and Electronic Systems Unit (UOSE) and PhD student of the Faculty of Science of the University of Porto (FCUP), currently doing research work at the University of Toronto (Canada), presented an article at the conference Photonics West 2010, in San Francisco, and was awarded with one of the Student Awards.

Entitled “Femtosecond laser fabrication of birefringent directional couplers in fused silica”, the article addresses the fabrication of directional couplers in fused silica written by femtosecond laser. This project enables a faster prototyping of these devices, which make it possible to make a division in the intended fraction of the propagated optical power, for instance, in an optical fibre. Furthermore, these power dividers make it possible to separate radiation according to polarization, and so they work as excellent polarizers on a certain wavelength.

The article was co-written with J. R. Grenier, P. R. Herman and J. S. Aitchison, of the University of Toronto, and Paulo Marques of UOSE and FCUP.
