Abstract

A mask layer is formed on a semiconductor substrate such that an elongate opening of the mask layer extends lengthwise at an angle relative to a [011] direction of the semiconductor substrate. A ridge waveguide structure including an active layer is formed within the elongate opening on the semiconductor substrate by a selective growth method using the mask layer as a mask. The mask layer is then removed, and a clad layer is formed over the ridge waveguide structure.
