Abstract

We demonstrate a kink and beam steering free operation of 0.98-mu m GaInAs-GaInP high-power ridge waveguide (RW) lasers utilizing channel ion implantation. The ion-implanted regions along the both sides of the ridge effectively suppressed the excitation of higher order lateral modes, which causes beam steering and kink. The maximum power without beam steering and kink hasbeen achieved over 250 mW for channel ion-implanted RW lasers with 1.8-3.7-mu m ridge width, compared to 120-mW maximum power without the channel ionimplantation.
