英文摘要	The invention relates to a coupling part (3) comprising at least one essentially planar coupling waveguide (31) formed on a coupling-substrate (30), the coupling-substrate having opposite waveguide- and substrate faces, the coupling waveguide or waveguides each having an output face, the coupling waveguides being adapted to be optically coupled to source waveguide or waveguides for supplying light power to the coupling part. An object of the present invention is to provide a cost-efficient scheme for integrating one or several light sources with optical waveguides with minimum loss of brightness and power. A further object of the invention is to facilitate the coupling of the light from a light source into passive or active application waveguides. A further object of the invention is to facilitate the coupling of the light from a light source module into passive or active application waveguides. The problem is solved in that the coupling part (3) comprises a) at least one elongate groove (32) in the form of a recess in the waveguide face, the groove being adapted to receive an elongated optical application waveguide (41), and b) at least one coupling waveguide (31) and at least one groove (32) are formed on the coupling-substrate (30) relative to each other so that the output face of the coupling waveguide is suitable for being side-coupled to an application waveguide (41) located in said groove. The invention further relates to a light source part and a light source module and to optical devices based on these parts. The invention may e.g. be used in high power fibre lasers or fibre amplifiers.
