英文摘要 | PURPOSE:To effectively avoid that a leakage current is generated by a method wherein the band gap of a current-blocking layer of a first conductivity type and a second clad layer of a second conductivity type is made larger than the band gap of a clad layer of the first conductivity type and a first clad layer of the second conductivity type. CONSTITUTION:A second clad layer 7 [p2] of a second conductivity type, e.g. a p-type, and a current-blocking layer 6 [n2] of a first conductivity type, e.g. an n-type, form a p-n junction; a first clad layer 5 [p1] of the second conductivity type and a clad layer 3 [n1] of the first conductivity type form a p-n junction via an active layer 4. The band gap of the regions p2 and n2 is larger than the band gap of the regions p1 and n As a result, even when a bias voltage corresponding to about a builtin potential of the p-n junction between the regions p1 and n1 is applied to a semiconductor laser, an electric current hardly flows to the junction between the regions p2 and n2 because a built-in potential of the p-n junction between the regions p2 and n2 is higher. It is possible to avoid that a leakage current is generated. |
