    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： An optically based resonating sensor useful for detecting and discriminating specified substances present in the environment is provided. The resonating sensor comprises a light source and a coupler adapted to allow light to pass from the light source to a resonator wherein the light is stored for a specified period of time. The resonator is coupled to the coupler such that some portion of the light passing through the coupler enters the resonator and some portion of the light resonating within the resonator exits the resonator to the coupler. The outer surface of the resonator is modified such that the interaction of the modified outer surface of the resonator with a specified substance in the environment alters some characteristic of the light flowing through the sensor system. A detector is arranged to observe and detect the interactions between the modified outer surface and the light flowing through the system.

    摘要： Resonant sensors and methods of detecting specific molecules with enhanced sensitivity. Optical energy is introduced into a microcavity, such as a silica toroid-shaped microcavity. The microcavity sensor has a functionalized outer surface and a sufficiently high Q value to generate an evanescent optical field with increased intensity. A molecule bound to the functionalized outer surface interacts with the external optical field, thereby heating the microcavity and generating a detectable resonant wavelength shift, which indicates a small number of molecules, even a single molecule, without the use of fluorescent or metal labels. Resonant sensors and methods can also be used to detect specific molecules, even a single molecule, within an environment. One application is detecting very small quantities or a single molecule of heavy water in ordinary water.
