    摘要： An optical device includes an optically emitting material producing spontaneous emission and an optical waveguide coupled to the optically emitting material. The spontaneous emission from the optically emitting material is emitted into at least one optical mode of the optical waveguide. The optical waveguide coupled to the optically emitting material does not provide optical gain, and the presence of the optical waveguide causes the spontaneous emission rate to be substantially more rapid than in the absence of the optical waveguide. The optical waveguide causes the more rapid spontaneous emission rate over a broad range of frequencies.

    摘要： Dimensional parameters of metal-containing structures such as films, interconnects, wires and stripes, and nanoparticles are detected using an approach involving plasmon-excitation and one or more metal-constituency characteristics of the metal-containing structures. According to an example embodiment of the present invention, plasmon-exciting light is used to excite plasmons in a structure, the plasmon excitation being responsive to the metal constituency. A characteristic of light reflected from the structure is then used to detect dimensional parameters of the structure. In one implementation, a characteristic of the reflected light that is related to the state of plasmon excitation in the structure is used to detect the dimensional parameters. In another implementation, the angle of incidence of the plasmon-exciting light is used in connection with an intensity-related characteristic of light reflected from structure to detect one or more dimensions of the structure. In still another implementation, the intensity of different wavelengths of the reflected light is used to determine one or more dimensions of the structure. With these approaches, the dimensions of a variety of structures such as metal films, interconnects, wires, and stripes are determined.

    摘要： Patterning planar photo-absorbing materials into arrays of nanowires is demonstrated as a method for increasing the total photon absorption in a given thickness of absorbing material. Such a method can provide faster, cheaper, and more efficient photo-detectors and solar cells. A thin nanowire can absorb many more photons than expected from the size of the nanowire. The reason for this effect is that such nanowires support cylindrical particle resonances which can collect photons from an area larger than the physical cross-section of the wire. These resonances are sometimes referred to as Mie resonances or Leaky Mode Resonances (LMRs). The nanowires can have various cross section shapes, such as square, circle, rectangle, triangle, etc.

    摘要： An optoelectronic device and method utilizing nanometer-scale particles arranged along a preselected path, each particle being capable of polarization. The particles are spaced apart such that polarization of one of the particles acts to induce polarization in adjacent particles, enabling electromagnetic energy to be transferred, modulated, filtered or otherwise processed by the device. In a specific embodiment, a chain of such particles may be arranged in a configuration having a variety of different angles, sharp corners and junctions, without adversely affecting device efficiency.
