Optical fiber for optically coupling a light radiation source to a multimode optical waveguide, and method for manufacturing it. Optical fiber for optically coupling a light radiation source (6) to a multimode optical waveguide (7) having an optical fiber core (2) for transmitting light waves, optical fiber cladding (3) enclosing the optical fiber core (2), an injection end face (4) of the optical fiber core (2) for injecting light emitted by the light radiation source (6) into the optical fiber core (2), an extraction end face (5) of the optical fiber core (2) for extracting light from the optical fiber core (2) into the multimode optical waveguide (7), the injection end face (4) of the optical fiber core being curved spherically inward in order to widen the radiation angle of the injected light.
