摘要： A Doppler compensation method is used for radio transmission between a mobile body possibly but not exclusively a train and some base station, both mobile body and base station comprise respectively a transceiver connected to an antenna for the radio transmission. The method comprises the step of determining the direction of motion of the mobile body with respect to the active base station i.e. the base station to which a radio transmission link is just built. The method is then followed by the step to apply a constant Doppler compensation corresponding to the cancellation of the Doppler effect for a mobile body moving in the same direction at predefined limiting speed of motion (vlimit) at which a quality threshold is reached with the used radio transmission technology in the case without a Doppler compensation.

摘要： A semiconductor laser in which the photons injected from its waveguide region into the laser active region are those whose energies differ from the energy sum of the chemical potential of the electron-hole pairs and the energy of the longitudinal acoustic phonons by less than one-half the thermal energy is described. A current directed into the photon emission region in the area of the Bragg grating causes photons of this energy to be injected into the laser active region which is constituted of a layer of indium gallium arsenide phosphide.

摘要： An integrated optoelectronic semiconductor component is presented, which can equally process light signals of any polarization direction. Such semiconductor components are used for digital optical telecommunications. The semiconductor component has active (A) and passive (B) waveguide sections, which comprise a number of semiconductor layers (SP) with so-called multiple quantum well structures. The semiconductor layers (SP) are deposited by a process known as selective area growth (SAG). A portion of the semiconductor layers has a lattice constant which is smaller than the lattice constant of a substrate (SUB). This creates a biaxial tensile strain in these layers. The tensile strain is optimized in the active waveguide sections (A) to attain polarization independence. Furthermore a process is described whereby such a semiconductor component can be manufactured.
