摘要： The present invention relates to a high-frequency signal transmitting optical module which can easily realize a high-frequency signal transmission by use of a semiconductor optical device to which a highly versatile metal can package has been applied. In the high-frequency signal transmitting optical module, after fixing, to a rear surface of a stem of the metal can package, fixing portions of the linear outer leads by laser welding, the end portions of the outer leads are bent. By this, the outer leads can be easily attached to the semiconductor optical device. On both sides of the respective lead pins of the semiconductor optical device, since the outer leads extending along these are attached to the rear surface of the stem, ground regions are continuously provided on both sides of the respective lead pins by the stem and respective outer leads, whereby TEM wave transmission lines are formed. Accordingly, high-frequency signals can be transmitted to the semiconductor optical device.

摘要： In optical module 10, light emitted from laser diode (hereinafter referred to as “LD”) 42 is collimated into parallel light beam by ball lens 44 and then travels through ball lens 26 to be focused on core 104 of optical fiber 100. Since the light passing between ball lenses 44 and 26 is the parallel light beam as described above, allowance is enlarged for axial misalignment between the optical axes of ball lens 44 and ball lens 26. This enables the light from LD 42 to be focused on core 102 of optical fiber 100 even if there occurs axial misalignment between the optical axes of optical fiber 100 and LD 42 due to a factor resulting from fitting of ferrule 102 into sleeve 14 or the like. Accordingly, there is no need for alignment in a work of mounting optoelectronic device 28, i.e., LD 42 in housing 12.
摘要翻译：在光学模块10中，由激光二极管（以下称为“LD”）42发射的光被球透镜44准直成平行光束，然后穿过球透镜26聚焦在光纤100的核心104上。由于在球透镜44和26之间通过的光是如上所述的平行光束，球面透镜44和球透镜26的光轴之间的轴向偏移的容限被扩大了。这使得来自LD 42的光能够聚焦在即使光纤100和LD42的光轴之间出现轴向未对准，由于将套圈102装配到套筒14等中的因素，光纤100也是如此。因此，在安装光电子器件28（即，壳体12中的LD 42）的工作中不需要对准。
