ABSTRACT:
An arrangement comprising a planarly extending thin-film waveguide, which is particularly useful when employed with devices that require a relatively high power and highly focused laser radiation. The arrangement comprises a planarly extending thin-film waveguide of a structure composed of a plurality of strip waveguides proceeding at a distance next to one another and a diffraction grating having rulings of a grating proceeding in a direction perpendicular to the running direction of the strip waveguides. The spacing between the neighboring rulings of the waveguides is equal to either the wave length of the wave being propagated in the thin-film waveguide or to a multiple of the wave length, and the wave is either an electromagnetic wave or an acoustical wave.
