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DWDM无源器件, 滤波片以及准分布式光纤温度传感领域.
此款产有3个波段可选, 分别覆盖1030~1070nm, 1525~1565nm, 1525~1607nm. 输出功率从10mW~200mW可选, 并且可以按用户要求将光谱平坦度控制在2dB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 so on.
