An edge-emitting diode laser based on the asymmetric Bragg reflection waveguide is reported, which utilizes Bragg reflectors as the n-doped waveguide. The optical field is confined in the low-index core layer through photonic bandgap (PBG) effect, resulting in large mode expansion and stable mode characteristics. The reduced overlap of the optical field and the p-doped total internal reflection (TIR) waveguide helps to increase the efficiency of the laser. The 3-μm-wide ridge lasers with uncoated facets demonstrated more than 160 mw and 400 mW power in continuous-wave and pulse operation respectively, limited by the thermal rollover. The operating wavelength of the laser is 995 nm. The device shows high threshold current characteristic temperature of 121 K. The calculated and measured far-field distributions in the vertical direction reveal that the laser operates at the PBG mode.
