Paper Abstract

By UV-laser irradiation the refractive index of some polymers can be locally increased in a controllable way. So by mask lithographic methods integrated-optical waveguiding and dispersive structures can be generated in the surface of a planar polymer chip. Thus a polymeric Bragg-sensor component in integrated-optical form was fabricated by the UV-light of an excimer laser. The surface morphology and optical-functional properties of the polymeric Bragg sensor component have been examined especially in dependence on the irradiation parameters and the temperature. The investigations yield the suitability of the Bragg-sensor for the measurements of temperature and deformation. For the realization of a passive fiber-chip coupling for the integrated-optical components a new technology has been developed and tested. The precise control and high-resolution ablation capability inherent in excimer laser machining make it ideally suited for creating grooves for passive alignment of optical fibers to planar channel waveguides.
