本文研究饱和非线性耦合器中脉冲传播的损耗动力学，发现输出相对能量流在特定非线性强度处出现峰值，且该峰值随耗散增强而减小并因Zeno效应消失。
AI 中文摘要
我们考虑了脉冲在饱和非线性耦合器中的传播，该耦合器的一个臂是耗散的，另一个臂是透明的。对于弱耗散值，能量从透明臂流向耗散臂，耦合器损失其能量。对于强耗散，耦合器的能量损失减少。这种能量损失依赖于饱和非线性。我们发现，在有限尺寸耦合器的输出端，相对能量的流动在特定非线性强度值处出现峰值。峰值随耗散的增加而减小，并且由于Zeno效应，在更强耗散下峰值消失。
英文摘要
We consider pulse propagation in a saturable nonlinear coupler whose other arm is dissipative and other is transparent. A flow of energy from transparent to dissipative arm takes place for weak value of dissipation and the coupler losses its energy. The energy loss of the coupler reduces for strong dissipation. This energy loss depends on the saturable nonlinearity. We find that the flow of relative energy at the output of a finite-sized coupler has a peak at a particular value of nonlinear strength. The peak value decreases with the increase of dissipation and it vanishes for stronger dissipation due to Zeno effect.
