UFTPR – Federal Technological University of Paraná 

UTFPR has a well-equipped facility for optical recording devices using laser beams, including chirped fiber Bragg gratings, which will also be used to record and adjust embedded nanophotonic devices. The recording facility has two pulsed excimer lasers (KrF and IRA), a pulsed laser in fs with optical parametric amplifier, and a continuous-wave UV Ar ion laser. These unique lasers, in combination with phase interferometers,  enable grating record.
