The results show that for arbitrary input elliptical polarization states, the resonance peaks in the band stop output characteristics of fiber optic ring resonator are splited into two groups corresponding to two polarization eigen states of the fiber. 结果表明,任意椭圆偏振态输入,光纤的双折射和扭转使光纤环形腔带阻输出特性中的谐振峰分裂为两组,对应于光纤的两个本征偏振态。
Based on this formula, the effects of the linewidth of input laser and the parameters of an active fiber ring resonator on the output linewidth were discussed. 从该公式出发,详细分析了环形腔输入光线宽和环形腔参数对输出光谱谱型和线宽的影响。
Under this condition, the input energy is entirely compensated for the loss of resonator. 在此条件下,耦合进入谐振腔的能量完全用于补偿谐振腔能量的损耗。
In the last part of this thesis, considering input threshold power distance of bistability switch point, input threshold power of bistability switch point, stabilization, switching time and so on, we design a erbium doped fiber ring resonator switch with double-directional coupler. 综合考虑开关阈值功率的间隔、开关阈值功率的大小、稳定性、开关转换时间等因素,选取适当的参数,设计了一个掺铒光纤环腔双稳开关。
