主动腔长调制对光纤环形腔有效带宽的影响

Effects of Loop Length Scan on Effective Bandwidth of a Fiber Optic Ring Resonator

首次从理论上导出了有腔长调制时光纤环形腔的输出特性，腔长调制对腔有效带宽影响的大小呈现出临界特性，得到了腔长调制速率大于临界值时有效带宽与调制速率之间的定量关系。计算结果成功地解释了当调制速率大于临界值时，腔的输出特性出现振铃和不对称现象。

For the first time, the output characteristics of a fiber optic ring resonator (FORR) with loop length scan are derived. The effects of the loop length scan appear a critical characteristics. The relation between scan rate and FORR effective bandwidth is obtained, which is held when scan rate is larger than the critical scan rate. The results calculated for different FORRs show that the ringing and asymmetry phenomena appear if the scan rate is larger than the critical rate.
