Package for housing optical semiconductor element and optical semiconductor device
A package for housing an optical semiconductor element includes a base body having an optical semiconductor element mounting portion on an upper main surface thereof; a frame body joined to the base body so as to surround the mounting portion; and an optical fiber securing member fitted in a through hole which penetrates through the frame body. The frame body is formed by bending a single strip-like plate member at its several positions, and then bonding one end side and an other end side thereof, the through hole being provided so as to be located at a juncture of the one end side and the other end side.
1. A package for housing an optical semiconductor element, comprising:
a base body having an optical semiconductor element mounting portion on an upper main surface thereof;
a frame body joined to the base body so as to surround the mounting portion;
an optical fiber securing member fitted in a through hole which penetrates through the frame body,
the frame body being formed by bending a single strip-like plate member at its several positions, and then bonding one end side and an other end side thereof,
the through hole being provided so as to be located at a juncture of the one end side and the other end side, and
a marking indicating a position coinciding with the juncture being provided on the outer peripheral surface of the optical fiber securing member.
2. The package for housing an optical semiconductor element according to claim 1 ,
wherein a joining material is continuously interposed in both of the juncture of the frame body and a region between an outer peripheral surface of the optical fiber securing member, and the one end side and the other end side.
3. The package for housing an optical semiconductor element according to claim 1 ,
wherein a part of the juncture of the frame body which extends from the through hole toward the base body is longer than a part of the juncture of the frame body which is located above the through hole.
4. The package for housing an optical semiconductor element according to claim 1 ,
wherein a seal ring is joined to an upper surface of the frame body.
