Paper Abstract

These last twenty years, advanced studies in integrated optics have demonstrated the capacity to elaborate optical circuits in planar substrates. Most of the optical integrated devices are realized on glass substrate and the guide areas are usually obtained by photolithography techniques. We present here a new approach based on the use of compounds photopolymerizable in the visible range. The conditions of self written channel creation by solitonic propagation inside the bulk of the photopolymerizable formulation are analyzed. Waveguides can be self-written in photopolymerizable materials1,2 due to the dependence of their refractive index on intensity and duration of the active light. This process results from the competition between the diffraction of the incident Gaussian beam and the photopolymerization which tends to increase the refractive index where light intensity is the highest. By controlling the difference between the refractive index values of the polymerized and non polymerized zones, the beam can be self-trapped along the propagation axis giving rise to a waveguide over distances as large as 10 cm without any broadening. Such permanent waveguides can be structured by inscription of gratings and doped with a dye in a plastic cell leading to the elaboration of a completely plastic laser.
