摘要 | PURPOSE:To obtain the titled element of a high luminous efficiency and high speed response excellent in mass productivity and suitable as the light source for optical communication by a method wherein the hole concentration of a P type GaAlAs active layer doped with Ge is set within a specific range. CONSTITUTION:A P type GaAlAs cld layer 2, a P type GaAlAs active layer 3 doped with Ge, and an N type GaAlAs clad layer 4 are formed by successive lamination on a P type GaAs substrate The first electrode 5 is formed on the lower surface of said substrate 1, and the second electrode 6 on the upper surface of said clad layer 4. In such a construction, the control of the hole concentration of said active layer 3 at 1X10cm-5X10cm causes the response at 20MHz or more and light emitting output at 2mW or more. The hole concentration of said layer 3 is in accordance with the doping amount of Ge doped to this layer 3, and the hole concentration can be easily controlled based on the condition for Ge doping. |
其他摘要 | 目的:获得具有优异的批量生产率的高发光效率和高速响应的标题元素,并且适合作为光通信的光源,其中掺杂Ge的P型GaAlAs有源层的空穴浓度设定在具体范围。组成:AP型GaAlAs cld层2,掺杂Ge的P型GaAlAs有源层3和N型GaAlAs包层4通过在P型GaAs衬底1上连续层压形成。第一电极5形成在下部所述基板1的表面和所述包层4的上表面上的第二电极6.在这种结构中,所述有源层3的空穴浓度控制在1×1017cm-3 -5X10 cm -3导致20MHz或更高的响应和2mW或更高的发光输出。所述层3的空穴浓度与掺杂到该层3的Ge的掺杂量一致,并且可以基于Ge掺杂的条件容易地控制空穴浓度。 |
