Patent ID: 6879757

Claim:
A method for coupling an optical fiber array comprising one or more optical fibers and an integrated optical waveguide array comprising one or more integrated optical waveguides upon a substrate having one or more fiber-mounting grooves therein, the method comprising: shaping an end face of the optical fiber array to have a first facet and a second facet, wherein the first facet has a first inclination angle substantially equal to an end wall inclination angle of an end wall of one of the one or more fiber-mounting grooves, and wherein the second facet has a second inclination angle substantially equal to a waveguide inclination angle of an end face of one of the one or more integrated optical waveguides; and mounting the optical fiber array on the substrate so that each of the one or more fibers rests in a respective one of the one or more fiber-mounting grooves, the first facet of each of the one or more fibers being aligned with the end wall of the respective one of the one or more grooves and the second facet of each of the one or more fibers being aligned with the end face of the respective one of the one or more integrated optical waveguides.
