提出了一种实用可行的控制光纤光栅波长的电磁调谐技术。实验表明 ,此调谐方法在 30 0mA电流下可达到 1 38nm的调谐范围 ,且具有较好的恢复性。可以应用于可动态配置全光分 /插复用器OADM系统中 ,也可用来对光纤光栅外腔激光器进行调谐和波长锁定 ,并可用于波长调制型传感器。
A practical and feasible electromagnetic tuning technology for controlling the wavelength of fiber grating is proposed. Experiments show that this tuning method can achieve a tuning range of 138 nm at 30 mA and has better recovery. It can be used in a dynamically configurable OIP / OADM system. It can also be used for tuning and wavelength locking fiber grating external cavity lasers and for wavelength-modulated sensors.
