Abstract
An optical coupler adapted to feed a plurality of optical fibers with light radiation coming from a single fiber or, conversely, to transmit to a single fiber the radiation coming from a plurality of fibers. A round paraboloid receives the optical beams condensed by hemispherical lenses placed in front of the fiber end faces and concentrates them on the end face of the output fiber through a hemispherical lens.
