    摘要: The present invention relates to a lensed fiber assembly having disposed therein an optical fiber, canted at an angle to the axis of light propagation, so as to adequately reduce back reflection of light into an optically active device coupled to the optical fiber. The design of the present invention enables quick and accurate alignment of the optical fiber with the active optical device by movement of the lensed fiber assembly either on axis with and/or orthogonal to the axis of light propagation.

    摘要: 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.

    摘要: Methods of preparing front and back facets of a diode laser include controlling an atmosphere within a first chamber, such that an oxygen content and a water vapor content are controlled to within predetermined levels and cleaving the diode laser from a wafer within the controlled atmosphere of the first chamber to form a native oxide layer hating a predetermined thickness on the front and back facets of the diode laser. After cleavage, the diode laser is transported from the first chamber to a second chamber within a controlled atmosphere, the native oxide layer on the front and back facets of the diode laser is partially removed, an amorphous surface layer is formed on the front and back facets of the diode laser, and the front and back facets of the diode laser are passivated.

    摘要: A connector assembly (10) for connecting a laser diode (14) and an optical fiber (12). The assembly (10) includes an optical connector subassembly (26) having an input for collecting optical energy emitted by the laser diode (14) and an output for transmitting a beam of the collected optical energy to the optical fiber (12), and attenuation means (24) between the input and the output for reducing the power of the beam of collected optical energy at the output to be transmitted to the optical fiber (12). A connector assembly of the present invention is effective in transmitting energy from a light source to an optical fiber with the same accuracy of alignment as a coupling of an optical fiber to an optical fiber; and, at the same time, is effective in controlling the power of the transmitted energy to protect against accidental injury due to inadvertent viewing of the light source when the optical fiber is disconnected from the assembly and to control the power of the optical energy entering the optical fiber.
