    • An optical semiconductor module having a large endothermic amount of an electronic cooling element can be provided, even if the area of the bottom plate of a package is the same. A package 11 includes two or more units of electronic cooling element 16 mounted therein. Each unit of the electronic cooling element is inserted through the space between inner juts 14a of ceramic feedthrough of the package 11 and a bottom plate 13, and is fixed to the bottom plate. The plural units of electronic cooling element are connected in series by one or more copper piece. The total area of junction between the two or more units of electronic cooling element and the bottom plate area of the package 11 occupies 75% or more of the area of the bottom plate. Thus, the ratio of the area of junction between the bottom plate and the electronic cooling element as a whole to the area of the bottom plate of the package can be increased.
    • 即使封装的底板的面积相同,也可以设置具有大的吸热量的电子冷却元件的光学半导体模块。 包装11包括安装在其中的两个或更多个电子冷却元件16。 电子冷却元件的每个单元通过包装11的陶瓷馈通件的内凸起14a和底板13之间的空间插入并固定到底板。 多个单元的电子冷却元件通过一个或多个铜片串联连接。 电子冷却元件的两个或多个单元与封装11的底板区域之间的接合面积占底板面积的75%以上。 因此,可以增加底板和电子冷却元件之间的整体面积与封装底板的面积的比率。
