摘要： A fiber coupled semiconductor device having an improved optical stability with respect to temperature variation is disclosed. The stability improvement is achieved by placing the platform holding the semiconductor chip and the optical fiber 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. Attaching the optical fiber to a vertical mounting surface of a fiber mount, and additionally 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.
