英文摘要 | In an active layer 15 of a semiconductor laser device 3, a refractive index type main waveguide 4 is formed by a ridge portion 9a of a p-type clad layer 17. Side surfaces 4g and 4h of the main waveguide 4 form a relative angle θ, based on a total reflection critical angle θc at the side surfaces 4g and 4h, with respect to a light emitting surface 1a and a light reflecting surface 1b. The main waveguide 4 is separated by predetermined distances from the light emitting surface 1a and the light reflecting surface 1b, and optical path portions 8a and 8b, for making a laser light L1 pass through, are disposed between one end of the main waveguide 4 and the light emitting surface 1a and between the other end of the main waveguide 4 and the light reflecting surface 1b. The optical path portions 8a and 8b are gain type waveguides and emit light components L2 and L3, which, among the light passing through the optical path portions 8a and 8b, deviate from a direction of a predetermined axis A, to the exterior. A semiconductor laser device and a semiconductor laser device array that can emit laser light of comparatively high intensity and can reduce side peaks are thereby realized. |
