Abstract

The mail goal of this project is to familiarize the student with the use of femtosecond laser pulses to fabricate waveguides in material. In this way, we intend to use femtoseconds lasers pulses to study the microfabrication process, induced by nonlinear interactions, in glassy and polimeric materials. In this context, initially we will determine the optimal conditions for microfabrication, such as pulse energy, scan speed and focalization to subsequently use this information to produce waveguides in polymers and glasses. Furthermore, the student will participate in the setup of a experimental system to couple light into waveguides, which will be then be used to characterized the fabricated waveguides.
