摘要

相比传统边发射激光器,垂直腔面发射激光器(VCSEL)光束质量高、可靠性高,在激光雷达测距(LiDAR)领域有广泛的应用前景。主要研究直插式TO(transistor outline)封装VCSEL和裸芯片VCSEL在窄脉冲大电流条件下的发光特性,通过Pspice参数扫描分析结合实验结果和理论计算,比较了两种封装激光器的杂散参数大小,并分析了其对激光器发光特性的影响。推导出了脉冲条件下VCSEL的功率转换效率公式,并分析了杂散参数对VCSEL功率转换效率的影响。

Abstract

The vertical cavity surface emitting laser (VCSEL) offers higher beam quality and reliability compared with the traditional edge emitting laser. It has significant application prospects in light imaging detection and ranging (LiDAR). The luminescence characteristics of a VCSEL with TO (transistor outline) package and a VCSEL with bare chip are examined under the narrow pulse and large current conditions. Using Pspice parameter scanning analysis, the experimental results combined with the theoretical calculation are used to compare the sizes of stray parameters and to analyze their effects on the luminescence characteristics of these two encapsulated lasers. Moreover, the formula about power conversion efficiency of a VCSEL under the pulse condition is derived and the influence of stray parameters on the power conversion efficiency of a VCSEL is analyzed.
