Method of aligning and attaching optical fibers to substrate optical waveguides and substrate optical waveguide having fibers attached thereto

摘要

A method of aligning and attaching optical fibers to substrate optical waveguides is disclosed. In accordance with the method, one or more slabs of preferentially etchable material and a waveguide substrate are placed adjacent each other face down on a flat surface for aligning the tops of the slabs with the top of the waveguide. A backing plate is secured to the back surface to hold the entire assembly together. The preferentially etchable material is thereafter etched to form v-grooves in alignment with the light guiding region of the waveguide substrate. Thereafter, optical fibers are secured thereto in an optically aligned manner with the light guiding region. In another aspect, the invention is directed to a fiber pigtailed waveguide substrate manufactured in accordance with the method.
