摘要： The invention relates to an optical waveguide (optical fiber) based on quartz glass having reduced internal mechanical stresses. In prior art optical waveguides, the internal mechanical stresses are primarily due to the production process, namely due to the difference of the linear thermal coefficients of expansion of the core and sheathing material during the cooling of the fiber and due to the drawing itself. In an inventive optical waveguide, the difference of the linear thermal coefficients of expansion of the core and/or sheathing material is selected by means of an appropriate doping of the core and sheathing material. This selection is made so that the internal mechanical stresses, which are caused by the cooling during the production process, are significantly reduced or eliminated and/or they counteract the stresses caused by the drawing. The invention provides that all of tile internal stresses inside the optical waveguide are significantly reduced, minimized or eliminated with regard to those of prior art optical waveguides. The advantageous effects resulting therefrom include a lower attenuation and improved PMD values compared to prior art optical waveguides.

摘要： A telecommunication system having frequency-dividing optical components where light pulses having different frequencies are coupled out of a optical fiber by fiber grating and/or photonic crystals and imaged by focusing elements outside of the optical fiber. The fiber grating for different frequencies can be used in a single period or in different periods disposed one after the other. The photonic crystals can be used at the optical fiber extremity or etched in a channel or trench in a glass fiber. Delay elements are added to ensure that different frequency light pulses are imaged simultaneously in a given and desired time relation as required for further parallel processing.

摘要： A method and device for reducing the distortion of optical pulses caused by the polarization mode dispersion in optical communication systems is provided. When an optical pulse having any polarization is transmitted through an optical communication system, which is optically anisotropic, at least in sections, the optical pulse may become distorted due to the different velocities of the various polarization components. This distortion of the optical pulses may reduces the maximum transmission rate of the system. A method is provided for functioning in response to the detected transmission quality of the communication system where a polarization-controlling device for setting the polarization of the optical pulse is driven in such a way that the transmission quality is maximized. An optical communication system, including an optical transmission medium, involves a device for determining the transmission quality of the communication system, a regulating device, and a polarization-controlling device. The output signal from the device for determining the transmission quality of the communication system may be applied to the regulating device, which drives the polarization-controlling device to change the polarization of the optical pulses in such a way that the transmission quality is optimized.

摘要： A method and an apparatus for generating a random number on a quantum-mechanics machanics basis using the fundamentally random choice of path of a quantum particle on a beam splitter. Detectors are provided for capturing the particles being assigned to the outputs of the beam splitter. The detectors or their counting events represent different number values of the random number, or random number sequence. The generation of a multi-particle state in the output channel of the beam splitter, and thus of several particles which impact on a detector (D1, D1′, D2, D2′), significantly and advantageously increases the response probability of the detector and thus the probability of obtaining a useable counting event for every multi-particle state generated by the particle source. In this way a random sequence can be obtained more rapidly and more reliably than with single-particle detection.

摘要： A method and a device are described to compensate for polarization mode dispersion in an optical transmission link(9, 9′) having polarization-dependent transmission characteristics, in particular in optical fibers and cables with not only statistical, but preferred birefringence. A compensation element (1, 1′, 1″), whose length is adjusted non-destructively using an interference device (2, 2′, 2″), in particular a pressure mechanism, is connected upstream or downstream from the transmission link (9, 9′). The polarization states PL and PS of the compensation element are mixed by the interference and thus the length of the compensation fiber is defined at which a propagation time difference between the partial waves of polarization states PL and PS is increased or decreased so that it compensates for the propagation time difference &tgr; within the transmission link (9, 9′).

摘要： A method and device for coherent addition of semiconductor laser emission, in particular for use in telecommunications. Individual emitters are coupled, each emitter to some extent experiencing some of the emission of all the others. Rather than all emitting independently of one another, the emitters are arranged in a common resonator. Using an optimization method, e.g., the simulated annealing method, the shape of the resonator mirror may be optimized until it optimally fulfils a preassigned set of mathematical requirements which constitute a set criterion. The individual emitters in the form of individual diodes, a diode matrix or a diode bar are arranged between two or more mirrors. At least one of these mirrors has a special, non-spherical surface that forms an internal correction element. Alternatively, the mirrors may be spherical-shaped with at least one non-spherical phase plate arranged in the resonator beam path. Outside the resonator a further system that includes a generator and a secondary beam shaper transforms the emitted beam so that it has the desired amplitude distribution and phase distribution and the desired irradiance.

摘要： A method and a device for reducing speckle formation on a projection display when working with a coherent light source. In this context, the light coming from the light source, before the projection, may strike an electrically controllable optical element having a spatially inhomogeneous refractive index, passing through the same, the refractive index being varied over time within the projection period. This may lead to an averaging out of the speckle pattern on the projection screen. For purposes of illumination, a multimode light source may be used, and/or the light coming from the light source is separated into a plurality of spatial modes, thereby reinforcing the effect. As an optical element, one may employ a liquid crystal element composed of at least two liquid crystal layers, to which a spatially dependent voltage is applied to generate a spatially dependent refractive index. Its birefringence may be compensated by orientating the layers to one another in appropriate fashion.

摘要： To provide directionally dependent attenuation for an optical information transmission link using simple means without the use of an active component, it is proposed to couple two optical waveguides (1, 2) having different core diameters to one another, the core diameter of the second fiber (2) being at least six times greater than the core diameter of the first fiber (1). In this manner, it is achieved that the conduction of light signals in a predefined direction is attenuated by at least the factor 30, while, on the other hand, the light propagating in the reverse direction, is attenuated very slightly.
