ABSTRACT:
A semiconductor laser having anti-guiding regions extending through the second confinement layer towards but not intersecting the active layer on both sides of the region of the confinement layer over a land between the grooves in the substrate. These anti-guiding regions serve to suppress higher order lateral optical modes by creating large radiative losses for these modes.
