Filed: 1991-09-04
Abstract: PURPOSE:To implement the light distribution feedback by a gain coupling by providing a cyclic structure for the distribution feedback adjacently to an active layer so that the conductiveness varies periodically in the axial direction of a laser light. CONSTITUTION:Diffraction gratings 7 are formed between a buffer layer 5 and a clad layer 8 in a conductive type which differs from that of these layers. In other words, while the buffer layer 5 and clad layer 8 are formed by an n-type semiconductor, for example, the diffraction gratings 7 are formed by a highly concentrated p-type semiconductor. The fundamental composition of the materials of these semiconductors are the same. Only the impurity doping in them differ from each other. The refractive indexes are also equal. With this structure, the density of the current passing vertically through the plane including the diffraction gratings 7 varies in the axial direction of the laser. Therefore, a carrier density distribution is formed on the active layer 4, and the gain coefficient against the optical wave which is propagated in the laser axial direction is varied in a cycle which agrees with the cycle of the diffraction gratings. Thus, it is possible to implement the distribution feedback by the gain coupling.
