Loss induced nonreciprocity

Webthe drift-induced non-reciprocity and twist-induced topologi-cal transitions. As the twist angle continues to increase, the flat degenerate bands split and undergo a hyperbolic-elliptic transition, similar to the photonic topological transition in ref[9]. However, all bands of heating and cooling modes un-dergo a similar topological transition (N Web11 de mar. de 2024 · Nonreciprocity is important in both optical information processing and topological photonics studies. Recently, scientists in China proposed a generic principle to realize nonreciprocity by using energy loss. As the phase lag induced by loss is independent of the energy propagation direction, by combining multi-lossy channels, …
