An arrangement of optical resonators which are composed of elongated optical waveguides comprising reflectors arranged at their end faces, one group of the waveguides being coupling resonators and a second group of the waveguides being useful resonators which are arranged in a substrate with the useful resonators being adjacent one surface thereof. A laser active material is provided adjacent the one surface of the substrate and can be either a semiconductor laser material or can be a light pump laser material. At least one of the waveguides of the useful resonators being composed of optically passive material, which has good wave-conducting properties, and being positioned adjacent to the laser active material so that a wave field excited in the waveguide can be intensified by the laser active material.
