摘要
为了更准确地表示VCSEL激光机的仿真模型,介绍常规建模方法,对实测数据的U-I进行拟合得出的函数关系联立其他经验公式建立激光器的数学模型,分析此种模型在L-I曲线斜率、阈值电流和输入电压这三方面的理想化处理对实际仿真模型的影响,并对这三方面建立新的U-IT模型从而得到激光器的数学模型。研究表明:使用新的模型与常规方法得到的模型相比,新模型与实测数据的吻合度更好,有助于提升激光器正常工作时的温度范围。
In order to more accurately represent the simulation model of VCSEL laser machine, a general modeling method is introduced in the paper. The mathematical relationship between the measured data U- I and other empirical formulas is established and the mathematical model of the laser is established. L-I curve slope, the threshold current and the input voltage of these three aspects of the ideal simulation of the impact on the actual simulation model, and a new U-IT model on these three aspects is established to get the mathematical model of the laser. The results show that the new model is better in agreement with the measured data than the model obtained by the conventional method, which helps to improve the tempera ture range of the laser during normal operation.
