ABSTRACT:
A method of forming an optical coupling device having plug pins received in a sleeve with one of the plug pins supporting a single waveguide and the other plug pin supporting a bundle of optical waveguides, characterized by providing the waveguides, etching the waveguides to form an end zone of a thin thickness connecting by a tapering transition zone having increasing thickness to the original cladding thickness of the optical waveguides, assembling the waveguides in an optical bundle with the end zones being arranged with the smallest spacing therebetween. Preferably, each of the plug pins has a bore with a small portion adjacent the end of the pin which corresponds to the diameter of the end zones of the bundle of waveguides.
