摘要： An optical modulator and related methods are described. In accordance with one embodiment, the optical modulator comprises a waveguide for guiding an optical signal, and further comprises a ring resonator disposed in evanescent communication with the waveguide for at least one predetermined wavelength of the optical signal. The optical modulator further comprises a semiconductor pnpn junction structure that is at least partially coextensive with at least a portion of a resonant light path of the ring resonator. The optical modulator is configured such that the semiconductor pnpn junction structure receives an electrical control signal thereacross. The electrical control signal controls a free carrier population in the resonant light path where coextensive with the pnpn junction structure. A resonance condition of the ring resonator at the predetermined wavelength is thereby controlled by the electrical control signal, and the optical signal is thereby modulated according to the electrical control signal.

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： A gated nanoscale switch operates as a resonant tunneling device. A conductive channel is formed of a pair of conductive molecular wires and a conductive nanoparticle. Each molecular wire is bound, at one end, to the conductive nanoparticle and, at the opposed end, to one of a pair of electrodes. The structure is located upon a dielectric layer that overlies a conductive substrate. The device may be arranged to operate as a switch with the conductive substrate acting as a gate electrode. Alternatively, the device may be employed to measure the electrical (current versus voltage) characteristics of the molecular wires.
