英文摘要 | PURPOSE:To reduce an operating voltage and to obtain an oscillation in a fundamental transverse mode over a wide range by a method wherein a substrate is constituted of Si and a buffer layer used to relax a discrepancy of a lattice constant is formed at an interface between Si and a compound semiconductor. CONSTITUTION:An n-type Si current-constricting layer 2 is formed on a p-type Si substrate 1; after that, a groove is formed by etching. Then, a buffer layer 3 constituted of one or several p-type AlGaAs layers is formed in order to relax a discrepancy of a lattice constant between AlGaAs and Si. In succession, a p-type clad layer 4, an active layer 5, an n-type clad layer 6 and an n-type contact layer 7 are formed. By this setup, a regrowth interface becomes flat; an oscillation in a fundamental transverse mode can be maintained over a wide range. In addition, an operating voltage can be lowered. |
