Abstract: A buried heterostructure type distributed feedback semiconductor laser comprises a semiconductor substrate (11) transparent to an oscillation light beam, a laser stripe including a diffraction grating, an active layer (14), and a guiding layer (13) formed on the semiconductor substrate (11), and semiconductor peripheral region (17, 18, 19) formed so as to cover the laser stripe on the semiconductor substrate (11). The semiconductor peripheral region is transparent to an oscillation light beam. Rectangular grooves (40) are formed near both side of emission facet of the laser stripe more deeply than the laser stripe. Since a radiation mode from the laser stripe is reflected and scattered by the grooves (40), it cannot hardly reach the emission facet. Therefore, the radiation mode does not interfere with an output beam from the laser.

Abstract: A method for operating a digital cellular mobile communication network for supplying mobile stations, located at continuously changing locations, from radio base stations via signal currents, uses a delay correction device which corrects for the delay differences of the signal currents produced by the radio propagation. The delay correction device consists of an adaptive transmission predistortion circuit which is arranged in the radio base station, it being possible for the distortion of the transmission predistortion circuit to be varied in accordance with the delay of the signals from the mobile station to the base station. As a result, the [lacuna] consuming relatively high power can be [lacuna] or greatly simplified or switched off, as a result of which the energy balance of the mobile station is improved and the production costs are lowered.
