摘要: A fiber coupled semiconductor device and a method of manufacturing of such a device are disclosed. The method provides an improved stability of optical coupling during assembly of the device, whereby a higher optical power levels and higher overall efficiency of the fiber coupled device can be achieved. The improvement is achieved by attaching the optical fiber to a vertical mounting surface of a fiber mount. The platform holding the semiconductor chip and the optical fiber can be mounted onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Optionally, attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device.

摘要: A molded ceramic or glass ferrule has at least one longitudinal passage, which enables an optical fiber feed through, sealed into a metal housing with glass solder. The metal material in the housing has a slightly higher coefficient of thermal expansion (CTE) than the ferrule material and the sealing glass so that hermetic seal is maintained by a compression stress applied to the ferrule and sealing glass by the housing at operating conditions. When the housing has to be fabricated from a low CTE material, e.g. metal or ceramic, a metal sleeve and stress relief bracket is used to apply the compression stress.

摘要: A fiber tail assembly (FTA) with a micro-lens formed in the fiber tip is used to couple the laser light out of the package and along the fiber. The FTA is soldered at two points where metallized bands are deposited on the fiber pigtail, one at a fiber mount near the diode where it can be soldered into alignment with the laser diode, and two at the snout which forms a feed through the housing and seal for the package. Typically, the FTA is metallized along its entire length within the package. In this invention the two-metallized bands are separated by a region that is unmetallized.
