    摘要： A semiconductor laser device in which semiconductor layers of an n-type cladding layer, a quantum well active layer 106, a p-type cladding layer, and an intermediate layer are formed on an n-type GaAs substrate in successive order, and a mixed-crystal is formed in a region except the semiconductor layers of the contact layer and the lower part of the contact layer by diffusing Si into the structure from above the intermediate layer, characterized in that the contact layer and the intermediate layer are made of n-type or nonconductive semiconductor material, and a p-type low-resistance region, formed by diffusing Zn into the structure from above the contact layer, is profiled so as not to overlap with the mixed-crystal region formed by Si diffusion.

    摘要： A semiconductor laser device which allows high speed correction of the position of a laser spot on an optical disk is disclosed. The semiconductor laser device comprises an active layer which oscillates a laser beam when electric current is supplied thereto, and a plurality of independent electrodes for varying the current density distribution in the active layer to vary the intensity distribution of the laser beam to be emitted from an emergent face of the semiconductor laser device. With the semiconductor laser device, by supplying electric currents individually from the plurality of independent electrodes to vary the current density distribution in the active layer, the beam spot position can be corrected within the frequency bandwidth of several tens MHz by direct modulation of the semiconductor laser device. Also a driving method for the semiconductor laser device and a tracking servo system in which the semiconductor laser device is incorporated are disclosed.
