摘要
从理论上导出了有线性腔长调制时光纤环形腔的输出特性，首次得到了腔长调制速率限的定量公式，并给出了调制速率大于速率限时腔的有效带宽与调制速率之间的关系．计算结果表明：当调制速率大于速率限时，腔的输出特性出现振铃和不对称．讨论了它在光纤环形腔陀螺中的应用．
The output characteristics of a fiber optic ring resonator (FORR) with linear loop length modulation are derived. The rate limit of the loop length modulation is presented for the first time. The relationship between the rate and the FORR effective bandwidth is obtained, which holds when the rate is larger than the rate limit. Computation results show that the ringing and asymmetry phenomena will appear in the output characteristics when the modulation rate is larger than the rate limit. Its application in FORR gyroscope is discussed.
