PURPOSE:To obtain a high output in a low current density without increasing the area of a semiconductor laser and with a leakage in a waveguide mode held back. CONSTITUTION:An active layer 3 formed on a substrate 1 and constructing a resonator has the shape of a flat surface formed by making the end parts of a plurality of rectilinear stripes intersect each other perpendicularly, and also it is so constructed as to comprise a reflecting mirror 9 which is the lateral surface of the active layer 3 located in the part of the perpendicular intersection of the rectilinear stripes and has an angle of 45 deg. to the directions of extension of the rectilinear stripes. |
