ABSTRACT:
To provide an optical transmission path coupling method and an optical transmission path coupling apparatus for preventing reduction in communication performance due to deterioration of optical elements and generation of dew as well as for accurately positioning the optical systems. An optical transmission apparatus includes guide pin holes provided on a Si substrate, and guide pins provided on an MPO connector and engaged with these guide pin holes to match mutual optical axes to thereby couple the optical transmission paths. Based on the guide pin holes, optical path windows, guide holes and bumps are formed. Pads for flip chip bonding in alignment with the bumps are formed on a light receiving element substrate. Based on these pads (based on the guide pin holes indirectly), light receiving elements are formed, and the optical axes of optical path windows and micro-lens array are matched by flip chip bonding.
