摘要:
为了研究多相移光纤光栅的光谱特性,探究其在光纤通信和光纤传感领域的应用,利用传输矩阵法,通过Matlab编程对多相移光纤光栅中等分相移光栅、相移级联光栅及混合相移光栅在不同相移个数、不同相移量大小、不同位置放置时的传输光谱特性进行了仿真和研究.结论表明:等分相移光栅可以通过增加相移个数来实现多波长的激光输出,相移量不同激光波长的输出也不同.相移级联光栅可用作带宽滤波器,通过增加相移光栅的级联数增加带宽.
Abstract:
The application of multi-phase-shifts fiber grating in fiber communication and fiber sensor are researched based on the analyses of the spectra characteristics. Using matrix approach and Matlab, the spectra characteristic of fiber grating in multi-phase-shifts fiber grating with equidistance phase-shifts、cascade phase-shifts and the mixed phase-shifts are analyzed with the conditions such as different phase-shifts number, different phase-shifts magnitude and different location of phase-shifts. Conclusions show that multi-wavelengths laser output can be achieved through increasing phase-shifts number and the laser wavelength varies with phase-shifts magnitude in multi-phase-shifts fiber grating with equidistance. The multi-phase-shifts fiber grating with cascade phase-shifts can be used as bandwidth filter and its bandwidth can be widened by increasing cascade numbers.
