英文摘要 | PURPOSE:To realize reduction of threshold current, and stabilization and uniformity of characteristics, by a method wherein current limiting by utlizing crystal anisotropy of carrier density or current concentrating by forming a current path is performed. CONSTITUTION:On the main surface of a substrate 1, for example, GaAs single crystal substrate, an inclined plane 2 is formed. Thereby the (100) crystal face and the one different from (100) face are made to face a main surface 1a. On these crystal surfaces, a III-V compound semiconductor layer is grown by, for example, an organic metal vapor phase epitaxy which is so-called MOCVD. A current concentration region 3 is formed in the manner in which a current path is limited by utilizing the difference of carrier density from each crystal surface to a growth region. Therefore laser light emission is generated by forming a local part in which the density of injected carrier is large, that is, a part of large gain. Thereby, a gain-guide type can be formed wherein the threshold current is small, and uniform stable characteristics are realized. |
