Abstract
A method of making an (In,Ga)(As,P) inverted rib waveguide laser in which a lateral waveguiding effect is provided by an inverted rib formed in intermediate index material spacing the active layer from the substrate which accommodates the rib in a channel in the substrate includes forming the channel with {111}B or {011} plane side walls, thereby permitting the use of a thinner intermediate index material layer than is possible when using a channel with {111}A plane sides.
