Abstract

In this project we propose the use of femtosecond pulsed lasers for fabrication of organic structures in micrometric and sub-micrometric scale by the photopolymerization assisted by two photon absorption. This promising method for devices microfabrication has been seen as a strong and useful tool for the confection of distinct type of systems, as photonic crystals, mechanic micro-devices, micro-resonator, and others. In this project, our objective is to produce microstructures optically active, by doping the acrylic resin with organic compounds which presents interesting optical process for photonic and optoelectronic devices. In a second stage, we intend to create and apply tapers of sub-micrometric fibers (nanofibers) to connect the microstructures, and also make the connection between the microstructures with external systems for excitation/detection. Finally, we also intent to develop all optical micro-resonators that could be integrated using the tapers previously developed, aiming the construction of all optical circuits.
