A modulated pseudo-Hermitian optical dimer is investigated. The parameter ranges are determined where the eigenmodes of the dimer conserve their power. It is shown that such a dimer has several exceptional points, and it is found that the dimer modes can conserve their average power over the period even if each of its segments is in the PT-broken phase. On the other hand, even if each segment is in the PT symmetric phase, the average power over the period is not conserved for the dimer. Thisspecial feature is determined by the relationship between the dimer length and the beat period of the signal in the individual segments of the dimer.

伪伪厄密二聚体

研究了一种调制的伪Hermitian光学二聚体。确定参数范围,在此范围内二聚体的本征模保存其功率。结果表明,这种二聚体具有几个例外点,并且发现,即使二聚体模式的每个片段均处于PT断裂相,该二聚体模式也可以在一段时间内保留其平均功率。另一方面,即使每个段都处于PT对称相位,二聚体也不会保留该周期内的平均功率。此特殊功能由二聚体长度和二聚体各个部分中信号的拍频周期之间的关系确定。
