    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： 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： Optical components may be aligned for transverse-optical coupling by: fabricating a first optical component on a substrate; fabricating an alignment member on the substrate suitably positioned relative to the first optical component; and assembling a second optical component onto the alignment member, thereby establishing transverse optical coupling between the optical components. The substrate may preferably be substantially planar. The alignment member may mechanically engage the second optical component so as to accurately establish and stably maintain transverse optical coupling. The first optical component and the alignment member may preferably be fabricated on the substrate using precision spatially selective materials processing techniques. Transverse optical coupling between two optical components may be stably maintained by substantially embedding transverse-coupled portions of the components in a substantially solid substantially transparent low-index medium. An alignment member may serve to accurately position the transverse-coupled components prior to embedding and hold them in place during embedding.
