ABSTRACT:
The configuration couples light into an end of a multimode optical waveguide through a pin stub of a single mode optical waveguide. In order to enable relatively wide-band signal transmission via the multimode optical waveguide, the pin stub has a light extraction region in which its cladding is surrounded by an outer coating of a material having a higher index of refraction than the index of refraction of the cladding material.
