    摘要： 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. The beam-splitter and the partial cylindrical surface reflect the laser beam portion deflected from the primary laser beam path onto a second photo-detector to provide a data stream from which the operation of the laser may be monitored, thereby insuring the proper transmission of the data signals provided to the laser through the lead frame and its associated electronic connections.

    摘要： 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.

    摘要： The present disclose provides methods and systems for positioning a fiber end of an optical fiber. A block is provided having an opening for receiving the optical fiber. The optical fiber is positioned in the opening to constrain the optical fiber in at least one direction. The optical fiber has a first portion with a free end which is cantilevered or extends from the block. The optical fiber is moved against the at least one direction which is constrained. The movement is provided from a position on a second portion of the optical fiber, which is opposite the first portion relative to the block. This movement causes a lateral displacement of the free end.

    摘要： A coupling arrangement includes a vertical cavity surface emitting laser. A carrier has the vertical cavity surface emitting laser affixed thereto. An optical coupler is coupled to the vertical cavity surface emitting laser, and has a plurality of optical fibers which receive light emitted from the vertical cavity surface emitting laser. The vertical cavity surface emitting laser is separated from the optical coupler by a gap and is free of direct contact with the optical coupler. The gap is less than about 50 microns, and is greater than zero microns. A curable adhesive is disposed in the gap for coupling the vertical cavity surface emitting laser to the optical coupler. The adhesive has a viscosity that defines a size of the gap.
