摘要： A groove assembly for holding at least one fiber optic. The assembly includes a base, a cover and a small carrier disposed between the base and the cover. The carrier has at least one groove. At least one fiber optic is disposed in this groove and terminates at an edge surface of the carrier. The base and cover have respective edge surfaces serving as attachment surfaces for attachment of the assembly to a planar lightwave circuit (PLC). The PLC has at least one waveguide terminating at an edge, to which the fiber requires alignment. The base and/or cover are preferably formed from a material enabling attachment to the PLC, e.g., transparent to energy used for curing an adhesive. The carrier is formed from material enabling a substantially more precise formation of the grooves, e.g., silicon.

摘要： 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.

摘要： An optical ON/OFF switch includes a micro-mechanical shutter formed on a silicon substrate using micro-mechanical fabrication techniques. The switch selectively opens and closes an optical path between two fibers with the micro-mechanical shutter. A micro-mechanical latch latches the shutter open or closed and remains in this state until electrical signals disengage the latch. Incoming and outgoing fibers are coupled to the shutter within the switch so that, when the shutter and the switch are ON (open) light couples between the ends of the two fibers. The fibers are positioned within stepped channels that hold each fiber along two edges within the channels so that the fibers are held in fixed alignment and relation. The fibers are laterally offset with respect to each other and the faces of the fibers are angled to limit back reflections from the shutter while still obtaining good coupling between the fibers.

摘要： The disclosed technique enables fully integrated monolithic hybrid optoelectronic chips to be built that combine electronic circuits, optical devices that are either flip-chip bonded or surface mounted on the VLSI circuits, and fibers. Disclosed is a technique for attaching a fiber optic pigtail to connect a silicon photodetector and a CMOS receiver (or a phototransmitter and a driver) to create a fully integrated CMOS receiver circuit for multimode fiber applications, such as those at a wavelength of about 850 nm. The integrated silicon detector/CMOS receiver can serve as a cheap power/signal monitor (for low speed applications) or even a high-speed Gigabit/s detector.

摘要： Even if there is a temperature variation, a positional discrepancy at a colliding surface of an active surface of a semiconductor laser and an optical waveguide is suppressed, resulting in realization of a semiconductor light emitting element coupled with optical fiber of stable operation. In order to realize the above object, a semiconductor light emitting element coupled with optical fiber comprises a substrate, an optical waveguide disposed on the substrate and including a core and a cladding layer covering the core, a semiconductor light emitting element disposed on the substrate and comprising an output end-surface facing one end of the core of the optical waveguide, and an optical fiber comprising a core an end of which faces the other end of the core of the optical waveguide, wherein the cladding layer sandwiches both surfaces of the semiconductor light emitting element.

摘要： A fusion joint between a waveguide (1a) and an optical fiber (2) is created by irradiating the interface (4) between the optical fiber and the waveguide using a laser beam. The spatial distribution of the energy furnished to the interface presents a central zone of which the energy is reduced with respect to a peripheral zone, whereby to enable a relatively high energy laser to be used while avoiding bending of the waveguide. The laser beam is caused to irradiate a higher energy density upon the waveguide than the optical fiber, typically by offsetting the center of the laser beam towards the waveguide. The fusion is performed while a force F urges the waveguide and optical fiber towards one another, so as to avoid the creation of a void at the boundary. A supplementary polymer or mineral joint can be provided. A method for multi-fiber fusion pigtailing more than a single optical fiber to respective waveguiding regions in a planar waveguide includes using a diffractive optical element (130) to produce a multiple energy distribution.
