VCSEL

垂直腔面发射激光器（VCSEL）是一种半导体激光二极管。与边缘发射激光二极管不同的是，VCSEL向上发射，因此可以很容易地封装成在单个芯片上包含数百个发射器的发射器阵列。

VCSEL的其他特性：

波长范围：650nm-1080nm，1550nm
功率范围：mW至瓦特
高调制带宽

VCSEL最初用于电信行业，如今已广泛用作传感应用中的光源。低功率（mW）应用包括面部和手势识别、接近探头、增强现实显示器。大功率（瓦特）应用包括用于机器人、无人机和自动驾驶车辆的LIDAR（激光雷达）。这些新应用程序由电池供电，需要将功耗降至最低。因此一定要对VCSEL功率、光束轮廓，噪声进行表征。 VCSEL通常与无源光学器件或扫描光学器件耦合，产生极宽的光束。另外，VCSEL通常采用脉冲模式。这些因素使得VCSEL测试和测量成为一项极具挑战性的任务。Ophir为此任务提供了合适的工具。
