英文摘要	PURPOSE:To enhance the efficiency of injection of currents into an active region and to increase modulation speeds by a method wherein a ring-geometry active region is constructed, inside a columnar protrusion, of an active layer same as the columnar protrusion in conductivity type and another active layer surrounding the columnar protrusion. CONSTITUTION:A ring-geometry active region AR is constructed, inside a columnar protrusion P, of an active layer including a double heterojunction built of a layer same as the columnar protrusion P in conductivity type and a diffusion region DR different in conductivity type from the active layer formed to surround the columnar protrusion P. In such a design, the active region AR is substantially reduced in size and, as the result, efficiency is increased in the injection of currents into the active region AR. Carriers may be efficiently contained in the active region AR, an enhanced-brightness light emission may be obtained, modulation speeds may be accelerated, and a higher output may be realized.
