    摘要: Miniature spectrometers produce low resolution spectral data due to their size limitations. A method for processing these spectral data is proposed. The spectral data from a low resolution spectrometer is enhanced to a higher resolution, or processed to be in the wavelength domain. This process is called spectrum reconstruction, and can be used in low cost and miniature spectrometers with limited spectral resolution. The proposed method is noise robust, adapts to input spectrum, and can be used across many types of spectrometric devices without any manual adjustment of parameters.

    摘要: In accordance with embodiments of the present invention, a nano structure optical wavelength filter is provided. A film made of a negative dielectric constant material such as a metal has embossing structures of subwavelength scale, located thereon in an array in a pattern. The array pattern and the structures are configured such that when light is incident on the array structures, at least one plasmon mode is resonant with the incident light to produce a transmission spectral window with desired spectral profile, bandwidth and beam shape.

    摘要: A tunable plasmonic filter or an optical filtering method discloses plasmonic filter structure and a voltage or current source. An intensity or wavelength of light transmitted through the filter structure is modulated by the intensity of a voltage or current from the voltage or current source. The plasmonic filter structure is located between electrodes electrically connected to the voltage or current source. The plasmonic filter structure is configured such that the incident light is resonant with at least one plasmonic mode on the structure, and a predetermined wavelength will perturb the metallic plasmonic structure in surface plasmon on energy bands for the wavelength selective transmission of light.
