Abstract
An optical semiconductor element is held in a junction-up state at an approach start position that is isolated from a mount face of a planar lightwave circuit, and the top-face height of the optical semiconductor element and the surface height of the planar lightwave circuit are aligned by bringing the optical semiconductor element closer towards the mount face. Further, the height of the active layer of the optical semiconductor element is aligned with the height of a waveguide of the planar lightwave circuit by bringing the optical semiconductor element towards the mount face for an amount of a difference between a reference value of a distance on design from the surface of the planar lightwave circuit to the center of the waveguide and a reference value of a distance on design from the top face of the optical semiconductor element to the center of the active layer.
