    • Optoelectronic components, specifically, ceramic optical sub-assemblies are described. In one aspect, the optoelectronic component includes a ceramic base substrate having a pair of angled (or substantially perpendicular) faces. The electrical traces are formed directly on the ceramic surfaces and extend between the pair of faces. A semiconductor chip assembly is mounted on the first face of the ceramic base substrate and a photonic device is mounted on the second face. Both the semiconductor chip assembly and the photonic device are electrically connected to traces on the ceramic base substrate. The semiconductor chip assembly is generally arranged to be electrically connected to external devices. The photonic devices are generally arranged to optically communicate with one or more optical fibers. The described structure may be used with a wide variety of photonic devices. It is particularly well adapted for use with vertical cavity surface emitting lasers (or laser arrays) and detectors (or detector arrays). In some embodiments, at least the cathode of the photonic device is soldered directly to a cathode pad on the base substrate. Similarly, in some embodiments, the semiconductor chip assembly is electrically connected to the base substrate by direct soldering. Specific base substrate structures are disclosed as well.
    • 光电子部件,特别是陶瓷光学子组件被描述。 在一个方面,光电子部件包括具有一对成角度(或大致垂直)面的陶瓷基底基板。 电迹线直接形成在陶瓷表面上并在一对面之间延伸。 半导体芯片组件安装在陶瓷基底基板的第一面上,光子器件安装在第二面上。 半导体芯片组件和光子器件都与陶瓷基底衬底上的迹线电连接。 半导体芯片组件通常被布置成电连接到外部设备。 光子器件通常布置成与一根或多根光纤光学通信。 所描述的结构可以与各种各样的光子器件一起使用。 它特别适用于垂直腔表面发射激光(或激光阵列)和检测器(或检测器阵列)。 在一些实施例中,光子器件的至少阴极直接焊接到基底衬底上的阴极焊盘。 类似地,在一些实施例中,半导体芯片组件通过直接焊接电连接到基底基板。 还公开了特定的基底结构。
