    摘要: 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 signal polarized 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.

    摘要: A resonant optical filter includes first and second transmission waveguides and a resonator (including one or more evanescently coupled resonator segments). The resonator supports at least one circumferential resonant mode and is evanescently coupled to the waveguides. An optical signal entering the filter through a waveguide and substantially resonant with the resonator is transferred to the other waveguide, while an optical signal entering the filter and substantially non-resonant with the resonator remains in the same waveguide. Multiple resonator segments may be formed on a common resonator fiber and positioned for enabling coupling between them, resulting in a tailored frequency filter function. The resonators may include alignment structure(s) (flanges, grooves, etc) for enabling passive positioning and/or supporting first and second transmission waveguides, such as optical fiber tapers. Structures may also be provided for suppressing undesired optical modes and/or resonances associated with the resonators and/or alignment structures on the resonator fiber.

    摘要: A fiber-ring optical resonator comprises a transverse segment of an optical fiber differing from adjacent segments in at least one physical property (e.g., diameter, density, refractive index, chemical composition, etc) so that it may support a resonant circumferential optical mode and enable evanescent optical coupling between the circumferential mode and an optical mode of a second optical element. The resonator may be fabricated with alignment structure(s) for enabling passive alignment of the second optical element for evanescent coupling, and/or with structure for suppressing undesired modes and/or resonances. A fiber-ring resonator may form a portion of a resonant optical filter or modulator. A plurality of optically-coupled fiber-ring resonators (formed on one or more fibers) may provide tailored spectral properties. Spatially-selective techniques for forming a fiber-ring resonator may include masking/etching, masking/deposition, laser machining, laser patterning, combinations thereof, and/or functional equivalents thereof.

    摘要: The present invention is a micro-cavity laser and methods related thereto. In the preferred embodiments, the micro-cavity laser comprises a laser pump signal in a fiber waveguide which is optically coupled to a micro-cavity resonator through a fiber taper. The micro-resonator includes a gain medium necessary for lasing action. The lasing frequency can be determined based upon the gain medium, the micro-cavity structure, as well as frequency selective elements such as gratings incorporated into the micro-cavity. The tapered fiber waveguide permits the micro-cavity laser to operate without a break in the fiber waveguide. In the preferred embodiments, the micro-cavity resonator is constructed from a doped silica or a semiconductor material. The present invention provides a compact laser with improved emissions and coupling efficiencies. Alternative configurations include multiple micro-cavities on a single fiber waveguide and/or utilizing multiple waveguides attached to one or more micro-cavity resonators. The laser can be made to operate in a continuous-wave as opposed to self-pulsing mode.

    摘要: 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.
