Self-induced Waveguides in Photopolymers Based On Plexiglass With Phenanthrenequinone — •Vladislav Matusevich, Elen Tolstik, and Oleg Kashin — Institute of Applied Optics, Friedrich-Schiller-University, Max-Wien-Platz 1, 07743 Jena, Germany

We present theoretical and experimental investigations of the self-trapping effect in photopolymers based on plexiglass with phenanthrenequinone. We show for the first time that it is possible to generate self-induced waveguides in this photopolymer. The behaviour of light propagation is explained with diffusion mechanisms of molecular redistribution. The waveguides are generated at 514nm (optimal Ar-laser power 10-50mW). Generation time is about 2-3 minutes. The waveguides can be fixated by UV curing illumination and can stay stable for years.
