论文摘要
在本文中，我们展示了如何在开放量子系统中设计的损失如何打破状态传播的互惠，以及如何实现不同类型的设计损失（包括线性和非线性的损失），如何实现非重生甚至单向传播。特别是，我们展示了如何在线性方案中的某些对称状态实现单向传播，这表明了通过将两种非线性设计的损失结合在一起来构建单模光学绝缘体的可能性，以及与构建非互联性循环器与散发式辅助辅助波动型波导的平面结构的方法。我们讨论了考虑的方案的可行性，并提出了可能的实现。
In this paper we show how designed loss in open quantum systems can break reciprocity of the state propagation, and how the non-reciprocal and even unidirectional propagation can be achieved for different kinds of designed loss, both linear and nonlinear ones. In particular, we show how a unidirectional propagation can be achieved for states of certain symmetry in linear schemes, demonstrate possibility of building a single-mode optical insulator by combining two kinds of nonlinear designed losses, and the way to build non-reciprocal circulator with a planar structure of dissipatively coupled waveguides. We discuss feasibility of the considered schemes and suggest possible realizations.
