Abstract

See full text

Provided is an optical device capable of bonding each optical part to a substrate with the same applied load by surface activated bonding even if the planar shape sizes of a plurality of optical parts to be mounted on the substrate are different from one another. The optical device includes a substrate, a plurality of optical parts different in planar shape size, bonded to the substrate by surface activated bonding adjacent to one another, and optically coupled with one another, and a plurality of bonding parts provided on the substrate in correspondence to the plurality of optical parts and including metallic micro bumps for bonding each optical part. The total area of the top surfaces of the micro bumps to be bonded to the corresponding optical part of each of the plurality of bonding parts is substantially the same.
