A grating-incorporated channeled-substrate-planar (CSP) laser is proposed for the 0° phase-shift mode selection. The 180° phase-shift mode is suppressed by combining fine gratings with the loss outside the electrode region. Single longitudinal mode oscillations of well-defined index-guided 0° modes are demonstrated for the wide channel CSP lasers.
