ABSTRACT:
An optical coupling device for optically coupling a laser light source with an optical waveguide having low coupling loss. A V-shaped groove is provided near an input end of an optical waveguide, and a short GI optical fiber is mounted in the V-shaped groove. By aligning the optical axes of the optical waveguide and the GI optical fiber, laser light emitted from a laser light source can be focused on a point on the input end surface of the optical waveguide by the optical beam focusing property of the GI optical fiber, caused by the parabolic distribution of the refractive index of the core of the short GI optical fiber in the radial direction. Leakage of the optical energy outside of the optical waveguide core can be prevented, and the laser light source and the optical waveguide can be optically connected with low coupling loss.
