Abstract:
An optical device assembly comprises a substrate with a component and fiber groove thereon. A segment of optical fiber is engaged with the fiber groove, which positions the fiber segment for optical coupling with a component on the substrate. A fiber retainer maintains the fiber segment in engagement with the groove. The fiber retainer may be secured to the substrate with adhesive means. Recessed regions formed on the substrate/retainer are filled with adhesive means, forming retaining members. Alternatively, the fiber retainer comprises a resilient member engaged with the device substrate and biased so as to urge the fiber segment into the groove. The resilient member may be variously configured and/or adapted for enhancing engagement of the fiber segment with the fiber groove. Either embodiment may include a housing, which may be variously configured and/or adapted for engaging a mating fiber-optic connector, providing fiber pigtail(s), mechanical splicing, and so forth.
Abstract:
A method for bonding first and second components (100, 200) to one another comprises: forming a plurality of bonding area projections (102) on a bonding area of a first component (100); depositing bonding metal (300) on the bonding area of the first component or a corresponding bonding area of a second component (200); positioning the first and second components (100, 200) with the deposited bonding metal (300) between their respective bonding areas and in contact therewith; and urging the first and second components (100, 200) toward one another, thereby pressing the deposited bonding metal (300) therebetween. The plurality of bonding area projections (302) protrude into the deposited bonding metal (300) after the bonding metal is pressed between the first and second components (100, 200). The first and second components (100, 200) are bonded to one another by each adhering to bonding metal (300). An apparatus comprises first and second components (100, 200) bonded according to the disclosed method.
Abstract:
An optical signal may be received into orthogonal linearly polarized modes of a transmission optical waveguide, the transmission waveguide including first and second transverse-coupling segments thereof. Optical signal polarized along one polarization direction may be substantially completely transferred from the transmission waveguide into a first transverse-coupled waveguide, the first transverse-coupled waveguide being optically transverse-coupled to the first transverse-coupling segment of the transmission waveguide. Optical signalpolarized along the other polarization direction may be substantially completely transferred from the transmission waveguide into a second transverse-coupled waveguide, the second transverse-coupled waveguide being optically transverse-coupled to the second transverse-coupling segment of the transmission waveguide. The optical signals carried by the first and second transverse-coupled waveguides may be combined into a single waveguide. The polarization directions of the transmission waveguide may be rotated about 90° between the first and second transverse-coupling segments
