PURPOSE:To make it easily realizable to couple this device with an optical fiber, by forming a second groove, which is positioned on an extension line of a striped luminous region and in which the optical fiber is inserted to be made fixable, on an optical fiber fixing part which is partitioned off from a luminous part by this groove. CONSTITUTION:A first clad layer 2, an active layer 3, a second clad layer 4, a cap layer 5, and the like are laminated on a semiconductor substrate 1, and a striped luminous region 9 is formed by burial crystal growth. A first groove 10, which is perpendicular to the striped luminous region 9 and deep enough to attain to the first clad layer 2, in such an edge emission type optical semiconductor device, so that a luminous part 15 and an optical fiber fixing part 14 are partitioned off. A second groove 11, which is positioned on an extension line of the striped luminous region 9 and in which the optical fiber is inserted to make fixable, is formed on the optical fiber fixing part 14. For example, the second groove 11 is formed equivalently to a clad diameter of the fixed optical fiber 12, and it is formed deeply so that a core part 16 of the optical fiber 12 is disposed on an optical axis extension line of the active layer 3. |
