Computer controlled laser beam recording techniques are used for the fabrication of V-shaped grooves in polymers. With a CO2-laser patterns are recorded which are suitable for the embedding of multimode polymer fibers with core diameters above 300 micrometers . Using a KrF excimer laser in a cylindric lens configuration V-grooves in PMMA are produced, where shape, width and depth of the grooves are highly reproducible and the parameters may be controlled by pulse energy and number of pulses with an accuracy of less than a micrometer. This method appears attractive for mounting monomode fibers.
