摘要： A liquid crystalline material having a lamellar structure can be used for phase modulation. A liquid crystal having arcuated or angular dimer molecules so that the molecules each include two central units, and the longitudinal axes of the two central units exhibit at least approximately oppositely directed inclination angles with respect to the layer normal z. By configuring the two central units of the dimer molecule in accordance with the present invention, the molecular index ellipsoid, which is essentially composed of the components of the two readily polarizable central units, may be positioned such that the optical axis is always situated in parallel to the layer normal z, making it possible to prevent the light, which propagates in a defined direction orthogonally to the layer normal through the liquid crystalline material, from undergoing a polarization modulation simultaneously with the phase modulation.

摘要： WDM multi-channel systems for large distances having a number of intensifiers may cause an increase in intensifications, which lead to considerable differences in intensity, even given modest wavelength dependence, making spectral leveling maybe necessary. The light from the fiber is first spectrally into channels, and, thus locally separated, projected onto the surface of an optic limiter based on an OASLM (optical addressed, spatial light modulator), in which the intensive channels are overproportionally attenuated. The tension dependence of liquid crystal cells, derived from exposure, is used to level the WDM channels. Lastly, the channels are again imaged onto a point and coupled into another fiber. The invention is used in WDM multi-channel systems for large distances a number of intensifiers.

摘要： The present invention relates to an optical single-mode fiber having low dispersion for the wavelength division multiplex operation (WDM) of an optical transmission path, which is made of a central fiber core having the radius r1, two inner fiber cladding layers having the outer radius r2 and a, respectively, where a>r2, and an outer fiber cladding layer, the refractive index profile n(r) of the fiber not being constant as a function of the fiber radius r (triple-clad fiber). By properly selecting the profile form and the refractive index differences between the core layers and cladding layers, respectively, conventional fabrication methods can be used to manufacture a fiber having low dispersion within the wavelength range of about 1400 to 1700 nm and, thus, in the third optical window, fiber attenuation not being increased thereby.

摘要： A double-beam interferometer for electromagnetic radiation and a method for the compensation of dispersion or increase in the spectral resolution of such an interferometer. Using a polarizer, which is brought into the optical radiation path, a defined polarization state P½0 is produced for the electromagnetic partial waves flowing into the arms of the interferometer. This polarization state is wavelength-independent and can vary for both partial beams. Optical elements modify the polarization state P½0 of the electromagnetic partial waves as a function of wavelength &lgr; and each spectral component &lgr;i is coded with a polarization P½ (&lgr;i). An analyzer, fitted to the output of the interferometer, transmits an adjustable polarization state Pdet, whereby an additional wavelength-dependent phase difference &ggr;(&lgr;) occurs between the partial waves of the spectral components. &ggr;(&lgr;) can be adjusted to obtain compensation of dispersion or an increase in the spectral resolution of the interferometer.

摘要： An intensity-dependent light modulating device or method for providing same, involves light successively passing through a polarizer, a first phase retardation plate and a first light modulator. The light then strikes a mirror and from there on, it passes once again through the light modulator and the phase retardation plate in the opposite direction and then strikes an analyzer that is crossed relative to the polarizer. The light modulator and the phase retardation plate are respectively located in an electric field in which the indicatrices of the light modulator and the phase retardation plate are deflected, wherein the deflection of the indicatrix of the light modulator is intensity-dependent. Due to the passage of light through the phase retardation plate and the light modulator, an intensity-dependent rotation of the direction of polarization occurs in such a way that higher intensity light is filtered in the analyzer while lower intensity light is transmitted. For example, a telescope is directed at an intensive light source in front of a dark background. The telescope only filters the intensive light source while the background can be simultaneously observed during almost the entire transmission.

摘要： A method and arrangement for generating binary sequences of random numbers uses the principle of random selection of the path of photons on a beam splitter and generating a random number by using two detectors (D10, D21) downstream from a beam splitter (ST2). To generate photons, a light source (L) of a low power is used, and an additional beam splitter (ST1) is connected upstream from the beam splitter (ST2). The photons emitted by the light source (L) during a predefined measurement time are split by the beam splitters (ST1, ST2) arranged one after the other in the beam path of the light source (L). The random sequence is generated when the splitting of the photons matches a predefined photon scheme.
