摘要	A semiconductor laser includes an active layer made of semiconductor; a ridge stripe having a cladding layer formed on the active layer and a contact layer formed on the cladding layer to protrude from the active layer; a pair of gratings each having a periodic structure in a longitudinal direction of the ridge stripe having a plurality of grooves each extending from side walls of the ridge stripe on flat portions in both sides of the ridge stripe; and absorbing layers covering the surfaces of the grooves of gratings to absorb excited light.
其他摘要	半导体激光器包括由半导体制成的有源层;脊形条纹，具有形成在有源层上的包层和形成在包层上的接触层，以从有源层突出;一对光栅，每个光栅在脊条的纵向上具有周期性结构，具有多个凹槽，每个凹槽从脊条的两侧的平坦部分上的脊条的侧壁延伸;吸收覆盖光栅凹槽表面的层以吸收激发光。
