摘要： An optical system can automatically lock an adjustable spectral filter to a first wavelength of an incoming light signal, and can automatically filter an additional incoming light signal at the first wavelength. A tunable filter can have a filtering spectrum with an adjustable peak wavelength and increasing attenuation at wavelengths away from the adjustable peak wavelength. The tunable filter can receive first input light, having a first wavelength, and can spectrally filter the first input light to form first output light. A detector can detect at least a fraction of the first output light. Circuitry coupled to the detector and the tunable filter can tune the tunable filter to maximize a signal from the detector and thereby adjust the peak wavelength to match the first wavelength. The tunable filter further can receive second input light and spectrally filter the second input light at the first wavelength.

摘要： A radiation-emitting device includes a nanowire that is structurally and electrically coupled to a first electrode and a second electrode. The nanowire includes a double-heterostructure semiconductor device configured to emit electromagnetic radiation when a voltage is applied between the electrodes. A device includes a nanowire having an active longitudinal segment selectively disposed at a predetermined location within a resonant cavity that is configured to resonate at least one wavelength of electromagnetic radiation emitted by the segment within a range extending from about 300 nanometers to about 2,000 nanometers. Active nanoparticles are precisely positioned in resonant cavities by growing segments of nanowires at known growth rates for selected amounts of time.
