Abstract
A semiconductor laser comprising a substrate with a pair of grooves in the surface thereof and a first confinement layer which overlies the surface of the substrate and has a terrace in its surface. An active layer overlies the surface of the first confinement layer and has a portion of maximum thickness and its recombination region over the concave portion of the terrace in the first confinement layer. A weak asymmetric positive index optical guide is thus formed which supports only the fundamental lateral optical mode.
