Abstract: An optical signal transceiver subassembly is mounted on a lead frame for further attachment to an electronic printed circuit board. The optical subassembly is comprised of a solid-state laser, a pair of photo-detectors, an over-mold of transparent material having shapes forming the exposed surface thereof, the surface and a selective silvering of a portion thereof defining a beam-splitter mirror and an interior reflective focusing surface, preferably in the shape of a partial cylindrical surface. The beam-splitter mirror is lightly silvered and the cylindrical surface is silvered to enhance the reflection of the laser beam. The optical subassembly is further enclosed with a housing incorporating a pair of lenses and alignment pins. The lenses focus the data stream of optical light signals onto the end of the outgoing optical fiber and the data stream of optical light signals from the incoming optical fiber onto and through the beam-splitter and onto a first photo-detector.

Abstract: An optical subassembly is provided. A mounting structure having a plurality of angled conductive traces is disposed on a first surface of the mounting structure. A holding device, coupled to a second surface of the mounting structure, has a plurality of optical channels. A laser optical device is electrically connected to the conductive traces on the mounting structure. An optical signal is emitted or received by the laser optical device and is converted to an electrical signal. The electrical signal is transmitted by way of the plurality of angled conductive devices to the plurality of optical channels.

Abstract: A fiber optic arrangement includes a chip, and a first light emitter and a second light emitter formed on the chip. A guide is formed on the chip and in registration with an active region of the second light emitter. An optical fiber is coupled to the second light emitter for transmitting light from the second light emitter. The guide aligns the optical fiber relative to the active region of the second light emitter. A light-sensing device is provided. An optical element transmits light emitted from the first light emitter to the light-sensing device for controlling an output optical power of at least the second light emitter.

Abstract: An opto-electronic module is housed in a hermetically sealed housing which is fabricated on a base member of solderable material to which a side wall structure is soldered. A cover is similarly provided that either is soldered to the top open end of the housing at the edge of the housing wall structure or is a cup-shaped member that slides over the wall structure and is soldered at the juxtaposed faces of the walls of the cover and the wall structure. Overlapping slots co-align to form a passage through which optical fibers may pass through the walls. The hermetic seal of the housing prevents the internal contamination of the module by water vapor, particulate matter or other contaminants.

Abstract: Parallel optical coupling apparatus for coupling a connector attached to one end of a parallel optical cable to a receiver or transmitter array. A parallel fiber optic assembly includes a receiver or transmitter array subassembly that houses a parallel optical coupler for transferring optical signals from an array of sources (e.g., lasers) in the assembly to the connector, or from the connector to an array of receiving elements in the assembly. A connector shell is provided that properly aligns the connector with respect to the optical coupler array.

Abstract: An optical coupler. The coupler has an optical element for transferring an optical signal from an entrance region, external to the optical unit, to an exit region, also external to the optical unit. The coupling element has a first substantially planar transmitting surface lying in a first plane, a second substantially planar transmitting surface lying in a second plane not coplanar with the first plane, a first substantially planar reflecting surface substantially perpendicular to the first transmitting surface, and a second substantially planar reflecting surface substantially parallel to the first reflecting surface, and a shaped reflecting surface substantially perpendicular to and adjoining the first and second reflecting surfaces.
