英文摘要 | PURPOSE:To obtain a laser device enabling basic mode to oscillate continuously at low current subject to room temperature by a method wherein a band-like P type GaAs epitaxial layer is provided on the surface of N type GaAs substrate to specify a conductive region. CONSTITUTION:A P type epitaxial layer 10 is laminated on (100) surface of mirror ground N type GaAs substrate 1 to open a hole with specified width in the (110) direction. Firstly N type GaAlAs layer 2, no additive GaAs layer 3, P type GaAlAs layer 4 and P type GaAs layer 5 are respectively deposited. The mixed crystal ratio at the layers 2, 4 is 0.3. Secondly, after evaporating Cr-Au layer 8 on the layer 5, the substrate 1 is chemically ground and adjusted up to specified thickness further evaporating Au-Ge-Ni layer 11 to complete the laser device. In such a constitution, the efficiency deterioration due to current expansion and absorption loss of rejunction radiation beams etc. may be prevented even at narrower width of conduction region to obtain a laser device enabling basic mode to oscillate continuously at low threshold value current. |
