摘要： An optical communication subassembly includes one or more optoelectronic devices, one or more optical elements, and a transceiver light coupling unit. Each optical element is configured to change a divergence of the outgoing light relative to a divergence of the incoming light and is spaced apart from and optically aligned with a corresponding optoelectronic device. The transceiver light coupling unit has a mating surface configured for mating with a connector light coupling unit attached to an optical waveguide. A mating direction of the optical light coupling unit forms an angle with the mating surface of the transceiver light coupling unit such that when the connector light coupling unit mates with the transceiver light coupling unit, the angle between the mating direction of the connector light coupling unit and the mating surface of the transceiver light coupling unit causes the optical waveguide to bend.

摘要： An optical sensing system and method is disclosed. In one embodiment, a method of detecting a scattering center includes the step of providing an optical sensing system including a light source, one or more bus waveguides where a first bus waveguide has an input port that is in optical communication with the light source, a microresonator optically coupled to the one or more bus waveguides, and a scattering center which is capable of optically coupling to the microresonator. The method further includes the steps of exciting at least a first resonant guided optical mode of the microresonator with the light source, altering a strength of optical coupling between the scattering center and the microresonator to induce a change in optical scattering between the first mode and at least a second guided optical mode of the microresonator, and detecting a change in transfer of energy from the first mode to the second mode.

摘要： An adaptive polarization mode dispersion compensator (102) including a polarization controller (110) and a differential polarization delay unit (130). The polarization controller converts incoming light (112) of an arbitrary polarization to a controller output signal having a desired state of polarization. The differential polarization delay unit is optically coupled to receive the controller output signal from the polarization controller. The differential polarization delay unit includes a polarization beam splitter element (125) and a first (132) and a second (132) birefringent optical waveguide. First (134) and second (138) chirped gratings are formed in the first and second birefringent optical waveguides. At least one tuning mechanism (180) is coupled to at least one of the gratings, wherein the tuning mechanism variably adjusts one of the reference reflection points (139) with respect to the other reference reflection point (135). A combiner element (125) recombines the two reflected orthogonal polarization signals into a delay line output (120). A signal quality analyzer (160) evaluates the quality of the differential polarization delay unit output signal and provides a control signal (164,166) to the polarization controller and the differential polarization delay unit.

The system further includes a microresonator configured so that the light source excites at least first and second resonant guided optical modes of the microresonator. The microresonator includes a first location on a surface of a core of the microresonator where a field intensity of the first mode is greater than a field intensity of the second mode. The microresonator core has a first cladding at the first location. The microresonator also has a second location on a surface of the core of the microresonator where a field intensity of the first mode is less than or equal to a field intensity of the second mode, the microresonator core having a second cladding at the second location. The first cladding is different than the second cladding.

摘要： Optical connectors are provided for connecting sets of optical waveguides (104), such as optical fiber ribbons to each other, to printed circuit boards, or to backplanes. The provided connectors (100) include a housing (110) that has an attachment area (102) for receiving and permanently attaching a plurality of optical waveguides. Additionally, the provided connectors include a light coupling unit (120) disposed in and configured to move with the housing. The provided connectors also include a second attachment area (108) for receiving and permanently attaching to the plurality of optical waveguides that causes each optical waveguide to be bent between the two attachment areas. The provided connectors utilize expanded beam optics with non-contact optical mating resulting in relaxed mechanical precision requirements. The provided connectors can have low optical loss, are easily scalable to high channel count (optical fibers per connector) and can be compatible with low insertion force blind mating.
