Abstract: A guided mode resonance (GMR) sensor assembly and system are provided. The GMR sensor includes a waveguide structure configured for operation at or near one or more leaky modes, a receiver for input light from a source of light onto the waveguide structure to cause one or more leaky TE and TM resonant modes and a detector for changes in one or more of the phase, waveshape and/or magnitude of each of a TE resonance and a TM resonance to permit distinguishing between first and second physical states of said waveguide structure or its immediate environment.

Abstract: A guided mode resonance (GMR) sensor that can be used to simultaneously detect an array of analytes. It provides a diagnostic system that can rapidly detect an array of biomarker proteins in patient samples (such as blood, serum or plasma for example) which can be used as an accurate means to conduct a differential analysis of proteins that allows the discrimination of early and late stages of disease, such as metastatic versus primary ovarian serous carcinomas. The GMR sensor can be provided in a compact size such that it can be portable.

Abstract: An exemplary embodiment provides a medical implant with implant surfaces that are exposed to body tissue when the medical implant is inserted into a body of a recipient. The implant has a micro- or a nano-sized pattern on at least a portion of the implant surfaces. Optionally, the micro- or nano-sized pattern may be a periodic (or “repeating”) pattern. Further, the micro- or nano-sized pattern may have geometric features, such as grooves, circles, triangles, rectangles, pentagons and hexagons.

Abstract: A downstream baseline optical signal generated by a baseline optical link is combined with a second optical signal generated by an additional optical link to generate a broadband optical signal. A fiber optic network splits the broadband optical signal to a plurality of fiber drops. An optical network termination unit receives the broadband optical signal from the fiber drop and isolates the downstream baseline optical signal and the second downstream optical signal from the broadband optical signal. An upstream baseline optical signal may also be transmitted through the fiber drop by the optical termination unit. The optical termination unit does not effect baseline optical service to any other optical termination unit in the fiber optic network.

Abstract: A method and apparatus for low cost upgrading on demand of an optical fiber communication system without installing additional optical fiber and minimal installation of optical circuitry at destination and distribution terminals. The upgraded systems comprise an optical data loop of a plurality of destination terminals and a single intermediate terminal.

Abstract: A single fiber passive optical network (PON) wavelength division multiplex (WDM) overlay includes a central office, a fiber optic network, and a plurality of optical network termination (ONT) units. The central office has a baseline optical link that receives a baseline communication signal and converts the baseline communication signal into a downstream baseline optical signal within a first optical bandwidth, and has an additional optical link that receives a second type of communication signal and converts the second type of communication signal into a second downstream optical signal within a second optical bandwidth. The downstream baseline optical signal generated by the baseline optical link is combined with the second optical signal generated by the additional optical link to generate a broadband optical signal. The fiber optic network is coupled to the central office and receives the broadband optical signal on at least one optic fiber.

Abstract: Methods of detecting one or more parameters of a medium are disclosed. The methods include providing a waveguide grating device, contacting the waveguide grating with a medium, propagating a signal having at least one signal attribute through the waveguide, and comparing the modified signal attribute to a known signal attribute to detect a parameter of the medium.

Abstract: An opto-electronic module has a platform and an optical sub-unit. The platform has a trough structure defined on a surface of the platform and the trough structure is configured to transmit an optical beam through the trough structure. The electrical sub-unit is coupled to the trough structure. The sub-unit is configured to mate with the trough structure to provide a chosen alignment to emit, operate on or receive the optical beam.
