摘要
取样光栅分布布拉格反射型(Sampled Grating Distributed Bragg Reflector,SGDBR)光源是一种电流驱动的波长可调谐激光光源。本文介绍了该光源的原理特性,通过搭建自动标定系统确立该光源驱动电流组合和输出光波长的对应关系,再将此对应关系用于电路设计中,并对该光源输出的光谱参数进行了实验验证,得到一种可用于光纤光栅解调仪表中的低成本波长扫描光源。
Sampled Grating Distributed Bragg Reflector( SGDBR) light source is a current driven wavelength tunable light source. This paper introduces the principle characteristics of the light source,through the platform of automatic calibration system to establish the relationship between the driving current and the output light wavelength,then the relationship are validated by experiment ally. We have successfully developed a low cost wavelength-scanning light source which can be used in the fiber Bragg grating interrogator.
