Abstract
Abstract A core region (107) with an end (114) and a cladding region (108) is formed. The cladding region (108) surrounds the end (114) of the core region (107) forming a surface (119) having a lens device (102) therein. The end (114) of the core region (107) is positioned with a selected distance (118) from the lens device (102) to the end (114) of the core region (107) of the waveguide (101). A light emitting device (103) having a working portion (104) is mounted on the surface (119) of the cladding region (108) with the working portion (104) of the light emitting device (103) directed over the lens device (102) for collection and focusing of light (109) from the working portion (104) of the light emitting device (103) into the end (114) of the core region (107).
