    Abstract: Inordinate localised systems are used at room temperature in a novel device in the form of an electron spectrometer for utilising single-electron electronic applications. Said electron spectrometer device consists of a nanocrystalline metal or a nanocrystalline semiconductor material used as conductor strip connection in the form of an inlet or an outlet for single-electron electronic components and circuits consisting of lithographically produced quantum dots. The resulting single-electron electronic device consisting of quantum dots is supplied with energetically very sharply defined electrons. Said device can thus be operated at room temperature, undisturbed by phonons.

    Abstract: The matter for which the refractive index is to be determined, is made available in the form of a theoretically determinable scattering or diffraction pattern. Two or more orders of diffraction may then be defined to form at least one intensity ratio. At least one intensity distribution may be formed by irradiating the scattering pattern using one light beam of a defined shape. Subsequently thereto, the intensity ratio may be formed based on the orders of diffraction of the intensity distribution. In addition, at least one portion of a characteristic curve may be determined, which represents the dependency of the intensity ratio on the refractive index, and, with whose assistance, the corresponding refractive index can be assigned to the intensity ratio formed.

    Abstract: One or more photonic crystals 11, 22, 40, 58, 59 are formed directly in the path of light within an optical fiber 13, 23, 42, 56. Light processed by the photonic crystal may be transmitted out of the fiber by means of a lens 48 or it may be measured by a photoresistive device 51, 60. The photonic crystal may be formed in a trench 12 as an array of dielectric rods 16 having one or more selective defects 17, or the crystal may be formed by providing holes 20 directly in the optical fiber. Filling the interstices between rods 16 with non-linear optical material, and subjecting the crystal to a varying electric field applied by electrodes or to a varying optical radiation can produce a tunable photonic crystal within an optical fiber.

    Abstract: The present invention is directed to an economical approach for compensating for the dispersion of optical signals having different wavelengths. In accordance with the present invention, photonic crystals (K1-Kn) are positioned on a common optical waveguide (2). In this context, each photonic crystal (K1-Kn) is tuned to reflect or deflect the signals of one wavelength and to transmit the signals of other wavelengths, unattenuated. The specific arrangement of the photonic crystals (K1-Kn) on the waveguide (2) and the specific arrangement of the deflecting elements in the photonic crystal are defined, in the process, as a function of the dispersion to be compensated for between the individual wavelengths. The approach of the present invention makes it possible to assemble permanently set or controllable photonic dispersion compensators of a high quality, which are approximately 1000 times shorter than conventional diffraction gratings.
