英文摘要 | PURPOSE:To intensify the light output as well as decrease the spreading angle of a radiated beam, by permitting the oscillation in a single mode, by providing a plurality of active layers with a necessary distance relationship thereamong, and by making the position of the maximum light intensify exist in the region having a large energy gap width outside the active layers. CONSTITUTION:Epitaxially grown on a semi-insulative or n type GaAs substrate 11 in a laminating manner are an n type Al0.35Ga0.65As clad layer 12 having an energy gap width larger than those of active layers 13 and 15, the n type GaAs active layer 13 having an energy gap width smaller than this, an n type Al0.2Ga0.8As cavity layer 14 having an energy gap width larger than that, the n type active layer 15 the same as the layer 13, an n type cavity layer 16 the same as the layer 14, and an n type GaAs cap layer 17. Then, carrier injection regions (a) and (b) are provided in the parts of the first and second active layers 13 and 15 where a p-n junction J crosses. In this case, the distance between the regions (a) and (b) is specified so that the rays of light emitted when a forward voltage is applied between electrodes 20 and 21 interfere with each other to become maximum as C marked with X. |
