摘要	The present invention provides a multiwavelength semiconductor laser capable of easily setting reflectance in a predetermined range at different oscillation wavelengths on a main emission edge face side. The multiwavelength semiconductor laser includes a plurality of semiconductor light emission parts of an edge emitting type having different oscillation wavelengths, and a reflection film provided commonly for main emission edge faces of the semiconductor light emission parts. The reflection film includes, in order from the semiconductor light emission parts, a first dielectric film (refractive index n1), a second dielectric film (refractive index n2), and a third dielectric film (refractive index n3), and the refractive indexes n1, n2, and n3 satisfy the relation of n3
其他摘要	本发明提供一种多波长半导体激光器，其能够在主发射边缘面侧上以不同的振荡波长容易地设定预定范围内的反射率。多波长半导体激光器包括多个具有不同振荡波长的边缘发射型半导体发光部分，以及共同设置在半导体发光部分的主发射边缘面上的反射膜。反射膜按照从半导体发光部件的顺序包括第一介电膜（折射率n1），第二介电膜（折射率n2）和第三介电膜（折射率n3），以及折射率n1 ，n2和n3满足n3
