On-chip artificial magnon-polariton device for voltage control of electromagnetically induced transparency

We demonstrate an on-chip device utilizing the concept of an artificial cavity magnon-polariton (CMP) generated via coupling between a microwave cavity mode and the artificial magnetism dynamics of a split ring resonator. This on-chip device allows the easy tuning of the artificial CMP gap by using a DC voltage signal, which enables tuneable electrodynamically induced transparency. The high tunability of the artificial magnon-polariton system not only enables the study of phenomena associated with the classical analogues of different coupling regimes, but also may open up avenues for designing advanced microwave devices and ultra-sensitive sensors.
