摘要	An optical coupling device is provided for coupling a pump light into an optical waveguide such as an optical fiber or planar waveguide. An optical source provides a pump light. A large diameter optical waveguide is arranged in relation to the optical source, has a diameter substantially greater than 0.3 microns, and includes a reflective surface that reflects the pump light and provides a reflected pump light to the optical fiber. The reflective surface may be either a notched surface of a V-shaped indentation or a cleaved end of the large diameter optical waveguide. Alternatively, the optical coupling device is includes a side tap lens mounted to the large diameter optical waveguide for directing pump light provided by the optical source. The side tap lens is arranged in relation to the optical source and includes a reflective surface that reflects the pump light and provides a reflected pump light to the large diameter waveguide, which directs the pump light to the optical fiber. The reflective surface may include a coated surface to enhance reflectivity.
