英文摘要 | PURPOSE:To prevent distribution non-uniformity corresponding to the distribution non-uniformity of from being generated in a refractive index at a region on an inverse mesa part where current flows and on an inverse mesa part of a semiconductor layer by forming the mesa part where a third semiconductor layer is extended in stripe shape with a sufficient width and height for emission. CONSTITUTION:A semiconductor layer 5 as a clad layer constituting a laminated body 2 has a mesa part 5' with sufficient width W2' and height for enabling a laser light to be emitted in a single mode and with a strength pattern having a single peak property. Therefore, since the tip surface which is terminated within the semiconductor layer 5 as a clad layer of a semiconductor region 8 as a layer for current constriction does not necessarily have uniformity, laser light which is obtained by irradiating toward the outside can be obtained with a strength pattern in single mode and with a single peak property even if distribution non-uniformity is observed on the mesa part 5' of a semiconductor layer 5, a semiconductor layer 4 as an activation layer, and a semiconductor layer 3 as a clad layer, and current flowing to a region on the mesa part 5'. |
