Semiconductor laser

   
   

A semiconductor laser includes a substrate; and a multilayered film formed on the substrate and including an active layer. The multilayered film includes a stripe structure that extends in a longitudinal direction of a resonator and has a tapered portion in which a width of a stripe changes in a tapered manner; and a first side face and a second side face that sandwich the stripe structure. At least one side face of the first side face and the second side face is inclined with respect to a principal surface of the substrate.
