However, oxide growth (above 435℃) follows a nonlinear law for the two geometry mesa structures which we employ in VCSEL.
但对于在VCSEL中采用的两种结构,氧化物的生长(温度高于435℃)表现为非线性生长行为。

We deduce the expressions of VCSEL and MMF modal field , known as Laguerre-Gauss functions, and give the formula of their modal radii.
首先得出了具有拉盖尔-高斯函数形式的VCSEL与MMF的模场表达式,并给出了相应的模场半径的计算公式;
1. VCSEL,全名为垂直腔面发射激光器(Vertical Cavity Surface Emitting Laser),以砷化镓半导体材料为基础研制,有别于LED(发光二极管)和LD(Laser Diode,激光二极管)等其他光源,具有体积小、圆形输出光斑、单纵模输出、阈值电流小、价格低廉、易集成为大面积阵列等优点,广泛应用于光通信、光互连、光存储等领域。
