Abstract
In a connection between an optical fiber or optical fiber array and an integrated optical waveguide or integrated optical waveguide array mounted or fabricated on a grooved substrate, an end face of an optical fiber array has a first facet and a second facet. The first facet has an inclination angle substantially equal to the inclination angle of an end wall of the substrate groove; the second facet has an inclination angle substantially equal to the inclination angle of the end face of the integrated optical waveguide. When the optical fiber array is mounted on the grooved substrate, each of the fibers rests in one of the substrate grooves. The first facet of each optical fiber end face is aligned with the end wall of the groove in which it rests, and the second facet is aligned with the end face of the integrated optical waveguide.
