英文摘要PURPOSE:To reduce a loss of light toward a side part of an active region and improve element characteristics by providing an antimelt-back layer at upper and side parts of the active region. CONSTITUTION:An n-InP buffer layer 12, an InGaAsP active layer 13, the first p-InGaAsP antimelt-back layer 14, and a p-InP clad layer 15 are formed on an n-InP substrate 11 in order. After that, a silicon dioxide masking 23 is used in the direction of and a mesa is formed by chemical etching. And then, the p-InGaAsP antimelt-back layer 16, a p-InP current constriction layer 17, an n-InP layer 18, a p-InP layer 19, and a p-InGaAsP contact layer 20 grow one after another and a p-electrode 21 and an n-electrode 22 are mounted. As to the active layer 13, therefore, the melt-back at its upper part is suppressed by the first antimelt-back layer 14 and the melt-back at its end face is suppressed by the second antimelt-back layer 16. Thus, no irregularities are formed at an interface between the active layer 13 and the current constriction layer 17 and then, this configuration prevents a light from leaking outside out of the active layer and improves element characteristics such as external differential quantum efficiency.
