Abstract
An optical fiber coupling, for example, an optical switch, for coupling a light source with a light-receiving end face of an optical waveguide comprises a lens for focusing a light beam emitted from the light source at a focal point on the light-receiving end face of the optical waveguide. An adaptive coupler positioned in the optical path is responsive to a beam steering control signal for steering and aligning the focal point relative to the light-receiving end face of the optical waveguide.
