【摘要】：提出一種雙錐型光纖光柵(FBG),利用傳輸矩陣方法分析了其漸變光柵區(qū)長(zhǎng)度和形狀對(duì)光柵反射譜的影響規(guī)律。研究表明:隨著漸變光柵區(qū)長(zhǎng)度的增大,兩主峰中間的次級(jí)峰幅值按不同比例增大,中間部分比例大,兩側(cè)比例小。當(dāng)漸變光柵區(qū)長(zhǎng)度增大1個(gè)數(shù)量級(jí)后,中間次峰有明顯的交聯(lián)趨勢(shì),隨著長(zhǎng)度進(jìn)一步增大,中間次峰完全連接在一起,并與兩個(gè)主峰等幅變化;漸變光柵區(qū)為線性和指數(shù)兩種形狀時(shí),雙錐型FBG光譜分布幾乎相同,而當(dāng)漸變光柵區(qū)為拋物線形狀時(shí),各次級(jí)峰右移至右側(cè)主峰兩側(cè),且幅度以主峰為中心逐漸降低。利用實(shí)驗(yàn)初步驗(yàn)證了理論分析的正確性。
[Abstract]:A double cone fiber grating (FBG),) is proposed to analyze the effect of the length and shape of the gradient grating region on the reflectance spectrum of the grating by using the transfer matrix method. The results show that with the increase of the length of the gradient grating region, the amplitude of the secondary peak in the middle of the two main peaks increases in different proportions, the proportion of the middle part is large and the ratio of the two sides is small. When the length of the gradient grating region increases by one order of magnitude, the intermediate sub-peak has obvious cross-linking trend. With the further increase of the length, the intermediate sub-peak is completely connected together, and the same amplitude changes with the two main peaks. When the gradient grating region is linear and exponential, the double cone FBG spectrum distribution is almost the same, but when the gradient grating region is parabola shape, the secondary peaks move to the right side of the main peak, and the amplitude decreases gradually with the main peak as the center. The correctness of the theoretical analysis is preliminarily verified by experiments.
