Abstract:
A method for mounting an optical device with a high degree of accuracy, the method comprising the steps of:providing a substrate including a mounting surface including phantom lines parallel to an optical axis;mounting an optical device to said substrate, said optical device including a surface facing said mounting surface when said optical device is mounted to said substrate;forming a plurality of first electrodes on said mounting surface and spaced from each other by a preselected distance to be connectable to said optical device;forming a plurality of second electrodes on said surface of said optical device and corresponding one-to-one to said plurality of first electrodes;connecting said plurality of first electrodes and said plurality of second electrodes with a plurality of first connection members;forming an optical waveguide on said surface of said optical device spaced from each of said plurality of second electrodes by a preselected distance;forming a third electrode on a part of said waveguide on said surface of said optical device;forming a fourth electrode on said mounting surface facing said third electrode when said optical device is mounted to said substrate;connecting said third and fourth electrodes with a second connection member; andforming a projection film on said mounting surface of said substrate such that said projection protrudes from a preselected portion of said mounting surface other than portions corresponding to said second and third electrodes and said waveguide of said optical device, said surface of said optical device being capable of contacting said projection thereby controlling a mounting accuracy of said optical device in a direction perpendicular to said optical axis.
