Abstract
A semiconductor optical device includes a stem; a semiconductor optical element mounted on the stem; a resin cap including a cylindrical body portion, a plate portion, and an edge portion; and a lens attached integrally to the plate portion of the cap. The edge portion of the cap is bonded to the stem so that the cap covers the semiconductor optical element. The cylindrical body portion of the cap has at least one first portion and second portions which are spaced apart from each other in the circumferential direction of the cylindrical body portion and which project inwardly relative to the at least one first portion. The stem has projections, and each projection vertically underlies and engages or contacts a surface of a respective one of the second portions of the cap.
