    摘要： Raman systems include a radiation source, a radiation detector, and a Raman device or signal-enhancing structure. Raman devices include a tunable resonant cavity and a Raman signal-enhancing structure coupled to the cavity. The cavity includes a first reflective member, a second reflective member, and an electro-optic material disposed between the reflective members. The electro-optic material exhibits a refractive index that varies in response to an applied electrical field. Raman signal-enhancing structures include a substantially planar layer of Raman signal-enhancing material having a major surface, a support structure extending from the major surface, and a substantially planar member comprising a Raman signal-enhancing material disposed on an end of the support structure opposite the layer of Raman signal-enhancing material. The support structure separates at least a portion of the planar member from the layer of Raman signal-enhancing material by a selected distance of less than about fifty nanometers.

    摘要： One embodiment of the present invention relates to a light-emitting diode having one or more light-emitting layers, a pair of electrodes disposed on the light-emitting diode so that an operating voltage can be applied to generate light from the one or more light-emitting layers, and at least one external electrode in electronic communication with the one or more light-emitting layers. Applying an appropriate voltage to the at least one external electrodes at about the time the operating voltage is terminated extracts excess electrons from the one or more light-emitting layers and reduces the duration of electron-hole recombination during the time period over which the operating voltage is turned off.

    摘要： An apparatus and related methods for modulating an electromagnetic radiation beam are described. A composite material is positioned in the path of the radiation beam, the composite material comprising a plurality of commonly oriented metallic first lines spaced apart by less than a wavelength of the radiation beam and a plurality of commonly oriented metallic second lines also spaced apart by less than that wavelength. The second lines are positioned in a crossing arrangement with the first lines, a crosspoint location being defined where each first line crosses each second line. An electrically programmable impedance memory element is positioned at each crosspoint location and is electrically coupled between the first and second lines corresponding to that crosspoint location, each impedance memory element having an electrically programmed state. The composite material modulates the radiation beam according to the electrically programmed states of the impedance memory elements.
