| 摘要 |
<p>A manufacturing method for an optical semiconductor device, including disposing a semiconductor element (3) that has a polarization dependent gain or polarization dependent loss between optical waveguide modes (TE, TM) differing in the direction of polarization, positioning a lens (4A, 6A) at one end face side of the semiconductor element (3) based on an optical coupling loss between the lens and the semiconductor element, and repositioning the lens based on the polarization dependent gain or the polarization dependent loss of the semiconductor element (3).</p> |
