  • 低偏振ASE宽谱光源 2um波段 覆盖1850~2000nm
  • 低偏振ASE宽谱光源 2um波段 覆盖1850~2000nm

低偏振ASE宽谱光源 2um波段 覆盖1850~2000nm

此类型的宽谱光源利用稀土光纤的放大的自发辐射(ASE)原理来获得极低偏振度特性. 典型偏振度5%以下, 对系统的偏振祥光效应基本没有影响, 尤其适合一些对偏振敏感的应用场合. 比如隔离器, 偏振片, 滤波片以及准分布式光纤温度传感领域. 输出功率10mW, 并且可以按用户要求将光谱平坦度控制在9dB以内. 可提供模块化及桌面型的产品形态.

DESCRIPTION

The ASE light source consists of pump laser and rare-earth doped optical fiber mainly. Spontaneous emission produced by energy level transition of the doped rare-earth ion is amplified by pump laser to generate stable broadband output. Different doped fiber and matched pump can be combined to provide various operating band, including 1060nm, 1550nm, 1590nm and 2000nm so on.
