Abstract: A method of using an external phone book memory card with a portable electronic device including an electronic address book with personal contact information, a memory card receiving slot, a memory card reader, and a display includes the steps of receiving an external phone book memory card in the memory card receiving slot, the external phone book memory card including phone book information stored thereon; reading the phone book information from the external phone book memory card with the memory card reader; and displaying the phone book information on the display.

Abstract: The present invention relates to a technique for fabricating a mechanical or visual alignment fiducial on a laser die particularly adapted for application with a laser die that is a buried structure edge emitting laser. In fabricating the device, the fiducial and the active mesa are formed in the same photolithography patterning step, using conventional techniques. The active is then buried with regrowth layers. The regrowth layers are subsequently selectively etched to expose the fiducial, leaving the active region protected and buried.

Abstract: An optical bidirectional link comprising: a module having a lower surface and an upper surface. The upper surface having disposed thereon a submodule having an optical transmitter and detector mounted thereon. Circuitry mounted on the upper surface. The circuitry having electronic components for effecting bidirectional communication via the optical transmitter and detector. A cover disposed over the upper surface of the module, wherein the submodule further comprises a silicon substrate having an optical fiber disposed in v-groove, a laser, reflective surfaces, and a holographic plate disposed on an upper surface of the silicon substrate.

Abstract: An apparatus for coupling an optical fiber to an optical device comprises a substrate and a passive alignment member. The substrate having a top surface and a bottom surface. The top surface having a fist groove disposed thereon for holding an optical fiber, and a second groove disposed on the top surface. The second groove being substantially orthogonal to the first groove. The passive alignment member disposed in the second groove. The passive alignment member having selectively etched forward and side pedestals for aligning the optical device to the optical fiber disposed in the first groove.

Abstract: A passive alignment structure for a substantially planar substrate, which is an anodic aluminum oxide structure having a vertical profile with respect to a horizontal surface of said substantially planar substrate.

Abstract: An improved connector is disclosed for interconnecting and terminating bundles of light transmitting fibers in such a manner as to have low light loss at the points of connection. The subject connector is suitable for use in either splicing or terminating individual bundles of light transmitting fibers, each bundle including at least one fiber, as well as for connecting a plurality of light transmitting fiber bundles in a single connector assembly. The subject connector includes an annular crimping ring, an annular cap member, and a profiled ferrule member all of which are slipped over the prepared end of a light transmitting fiber bundle. The end of the bundle is prepared by stripping the exterior layer therefrom to expose the light transmitting fibers. In the case of the bundle including a plurality of fibers, it may be preferable to also pretreat the bundle by applying a potting compound to the fibers to form them into a cohesive unit.
