A device integration method and integrated device. The mechanism includes link mechanism units which extend and retract the table main body relative to the base by a link movement, an operation part which is connected to the link mechanism units and operates the link mechanism units, and a cancel mechanism unit which prevents the link mechanism units from being operated without through an operation of the operation part. The first through third waveguides are arranged on one side of the substrate in the vicinity of the first portions of the first and second SOAs.
