Abstract
PURPOSE:To obtain an optical guide layer having higher refractive index than that of a second clad layer and to enhance its output by forming a stripelike groove for specifying an optical guide region narrower than the opening width of the stripelike groove formed on a current block layer on the second clad layer of the side not provided with a current block layer. CONSTITUTION:A current block layer 12 is formed on a substrate 11, and a stripelike groove 20 exposed with the substrate 11 is formed in the bottom. Then, a first clad layer 13, an active layer 14, a second clad layer 15, a stripelike groove 21 formed on the second clad layer 15, an optical guide layer 16, and a contact layer 17 are formed. A laser light generated in the layer 14 is enclosed in a region which approaches a region having an effectively large refractive index, i.e., the layer 16. The effective refractive index distribution added with the layer 16 becomes a refractive index which exhibits a double protrusion shape.
