    • An optical connection for connecting an active optical device (6,52) or a passive optical device (41,63) to an optical fiber (3), having a thick metal coating (2) deposited circumferentially around the fiber. In this optical connection the device (6,52,41,63) is bonded to the polished endface of the fiber (5), with particular use being made of the thick metal surface (7) on the endface of the fiber. In another embodiment, the optical fiber (3) is etched to form various surfaces (31,32,33) for optical coupling. This etching also allows for accurate passive alignment of an etched active device (52) or a passive device (42,63) with the optical fiber.

    • A buried hetero-structure laser diode is disclosed. The buried hetero-structure is formed by growing a double hetero-structure on a substrate. The double hetero-structure comprises two cladding layers spaced apart by a narrow bandgap active layer. Two spaced apart channels are etched in the double hetero-structure down to the lower cladding layer to define a mesa therebetween. Current blocking layers are deposited in the channels and on the portions of the double hetero-structure located outside the channels. The liquid phase epitaxy growth conditions are such that while the blocking layers are deposited in the channels and outside the channels, the upper cladding layer portion of the mesa is being melted back. Thus, the ends of the blocking layers touching the melted back mesa are separated from the active layer portion of the mesa by a thickness substantially less than the thickness of the upper cladding layer as measured in the regions outside the channels.
    • 公开了一种掩埋异质结激光二极管。 通过在衬底上生长双异质结构形成掩埋异质结构。 双异质结构包括由窄带隙活性层隔开的两个覆层。 两个间隔开的通道在双异质结构中被蚀刻到下包层以在其间限定台面。 电流阻挡层沉积在通道中以及位于通道外部的双异质结构的部分上。 液相外延生长条件使得当阻挡层沉积在通道中并在通道外部时,台面的上包层部分被熔化。 因此,接触熔化的背面台面的阻挡层的端部从台面的有源层部分分离的厚度基本上小于在通道外部的区域中测量的上包层的厚度。
