    摘要： Optical devices including waveguide grating structures are described. In accordance with one embodiment, an optical device is provided comprising a horizontal waveguide grating structure having at least one waveguiding layer and at least one subwavelength periodic grating layer. The optical device further comprises upper and lower cladding layers immediately adjoining respective upper and lower surfaces of the waveguide grating structure and having refractive indices lower than a lowest-index one of the waveguiding layers, incident radiation propagating through one of the upper and lower cladding layers toward the waveguide grating structure. The waveguide grating structure is configured for peak reflection of the incident radiation at a peak reflection frequency. A cumulative thickness of the waveguiding layers is less than one tenth of a free space wavelength of the incident radiation at the peak reflection frequency divided by an average refractive index of the waveguiding layers.

    摘要： A system can include a transmitter that produces an optical signal having a plurality of carrier frequencies and a receiver separated from the transmitter by free space through which the optical signal propagates. The receiver includes an array of detectors of multiple types, with the types being capable of detecting light respectively having the carrier frequencies. A location of an incident area where the optical signal is incident on the detector array generally depends on a misalignment of the receiver relative to the transmitter, but the detectors in the detector array are arranged so that at least one detector of each of the types detects light from the optical signal regardless of where the incident area is on the detector array.

    摘要： An angle sensor, system and method employ a guided-mode resonance. The angle sensor includes a guided-mode resonance (GMR) grating and a resonance processor. The resonance processor determines an angle of incidence of a signal incident on the GMR grating. The resonance processor uses a guided-mode resonance response of the GMR grating to the signal to determine the angle of incidence. The angle sensing system includes the GMR grating, the resonance processor and further includes an optical source that produces the signal. The method includes providing a GMR grating, detecting a guided-mode resonance produced in the GMR grating when subjected to an incident signal, and determining an angle of incidence of the incident signal from one or both of a number of and a spectral distance between guided-mode resonances present in a response of the GMR grating to the incident signal.

    摘要： A sensing system can include one or more particles having one or more plasmon resonances. The particles can be positioned adjacent to the active region of a sensor to enhance the sensitivity of the sensor to electromagnetic radiation having frequencies corresponding to the plasmon resonances. An array of sensors such as used for color imaging can employ different types of particles adjacent to different sensors, so that different sensors sense different colors. During fabrication of such sensors, the particles can be applied mechanically or using a process such as inkjet printing.
