摘要
为给不同参量的倾斜布喇格光纤光栅(TFBG)级联提供依据,通过传输矩阵法对FBG级联后的传输谱进行理论分析,利用光学仿真软件模拟了倾斜角度、光栅周期和级联相对位置不同对级联光栅(2段光栅)传输谱的影响。分析仿真结果可以得出:倾角、光栅周期及级联相对位置的不同对传输光谱均有影响,会不同程度地引起谐振峰的深度变化或中心波长的漂移,因此可以通过改变级联TFBG的参量来实现不同特性的传输谱。
In order to provide a theoretical basis for two stages of tilted fiber Bragg gratings(TFBG) with different parameters,this paper theoretically analyzes the cascaded FBG transmission spectrum by the transfer matrix method,and optical simulation software studies the effect on the transmission spectrum of cascading gratings(two gratings) when the tilt angle,grating period and cascade position are different.By analyzing the simulation results,it can be concluded that the transmission spectrum is affected by these parameters,which will cause the depth variation of the resonance peak or the drift of the center wavelength to varying degrees.Therefore,the parameters of the cascade TFBG can be changed to achieve the transmission spectrum of different characteristics.
