| 摘要: |
| 主要对基于垂直腔面发射激光器（VCSEL）的光功率-电流模型（L-T）可靠性进行了研究.综合运用非线性最小二乘法、多项式拟合及数值计算等方法，估计模型的相关参数，建立了一个比较接近实际的VCSEL光功率-电流模型.仿真结果表明：在20℃条件下，基于该模型的VCSEL温度特性与模型参数基本吻合，从而证明了模型是可靠的. |

| Abstract: |
| We study the reliability of light power and intensity of current (L-I) model of Vertical Cavity Surface Emitting Laser (VCSEL). We use the methods of nonlinear least squares, polynomial fitting and numerical calculation to estimate the model of parameters. The simulation shows that the characteristics of the temperature of VCSEL is almost the same as the model under 20℃. It proves the model is reliable. |
