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. |
