[0056] An optical device 1A of the second embodiment will be described. Figure 4 A is a plan view showing an optical device 1A of the second embodiment. Figure 4 B is a side view of the optical device 1A. The optical device 1A differs from the optical device 1 of the first embodiment in that it has a package fixing portion 19 arranged to cover the package 3 . Hereinafter, the package fixing portion 19 will be described in detail.

[0057] The package fixing part 19 covers the package 3 from the front end surface 8a via the upper surface 8e to the rear end surface 8b. The package fixing portion 19 has a first flange portion 21 , a second flange portion 22 , and a pressing portion 23 . The first flange portion 21 is disposed so as to protrude from the front end surface 8a side along the mounting surface 2a. The second flange portion 22 is disposed so as to protrude from the rear end surface 8b side along the attachment surface 2a. The pressing portion 23 connects the firs...

Abstract

An optical apparatus comprises a package containing an optical device and having a front end face provided with a through window part 11 to which an optical fiber optically connected to the optical device is attached, a base having an attachment surface for attaching the package, a first extension arranged so as to project from the front end face along the attachment surface, and a package securing member having a tilted surface adapted to abut against the package so as to generate a force for pressing the package against the base. The package securing member is independent of the package.

Description

technical field [0001] The present invention relates to an optical device in which a package housing an optical device is mounted on a housing. Background technique [0002] Patent Document 1 (Japanese Unexamined Patent Publication No. 5-327031) describes an optical semiconductor module in which a semiconductor element is incorporated. This optical semiconductor module includes a housing main body that accommodates a plurality of optical elements such as laser diode elements. A pair of flanges are provided at both ends in the length direction of the housing main body. A through hole is formed in the flange. The through hole is used for fixing the optical semiconductor module to the housing. [0003] 【Prior technical literature】 [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 5-327031 [0006] 【Problems to be solved by the invention】 [0007] Most of the optical devices are accommodated in packages having flanges, and...
