The laser (100) has a resonator (140) formed on a substrate (101) and emitting a laser beam from an emitting surface (108) formed on an upper surface of the resonator. The resonator has an active layer sandwiched between two mirrors (102,104). A reflectivity adjustment layer (110) formed on the emitting surface has an optical thickness (2Xm2-1)Xlambda . A mirror has a layer with optical thickness is m1Xlambda 1/2. Independent claims are also included for the following: (a) a light transmission device having a light module including an optical wave guide and the surface emitting semiconductor laser (b) a method of manufacturing a surface emitting semiconductor laser. |
