Abstract

Polymer lightguides ofPMMA, doped with azo dyes are investigated with respect to their opto-optical or all optical properties. The TRANS-CIS photoisomerisation of the azo dyes leads to reasonable polarization dependent optically induced refractive index changes. These are studied in planar lightguides and in leaky guides. With light at the absorption edge all optical properties are studied leading to a possible application as bistable device.
