| 中文摘要 | we report an experimental and theoretical study of maximum modal gain of p-doped 1.3 mu m inas/gaas quantum dot (qd) lasers. the maximum modal gain of the qd laser with five stacks of qds is as high as 17.5 cm(-1) which is the same as that of the undoped laser with identical structures. the expression of the maximum modal gain is derived and it is indicated that p-doping has no effect to the maximum modal gain. we theoretically calculated the maximum modal gain of the qd lasers and the result is in a good agreement with the experimental data. furthermore, qds with lower height or smaller aspect ratio are beneficial to achieving a greater maximum modal gain that leads to lower threshold current density and higher differential modal gain, which is good for the application of p-doped 1.3 mu m inas/gaas qd lasers in optical communications systems. |
