Abstract
Electromagnetically induced transparency (EIT) and electromagnetically induced absorption (EIA) have many applications, especially for achieving slow light and fast light. EIT and EIA have been widely observed in both quantum and classical systems where two transition pathways could interference destructively or constructively. Multipathway interference has been a concern in recent works, however, due to the difficulty of precisely controlling the system parameters, the experimental study of multipathway interference is generally challenging. In this paper, we explore a coupled high-temperature-superconducting (HTS) resonator platform for implementing three-pathway electromagnetically induced transparency (TEIT) and absorption (TEIA). In our system, both resonant frequencies and linewidths (loss) of each resonator as well as their coupling strength can be precisely controlled, thus TEIT and TEIA can be implemented as a set. Our proposed method shows great potential for use in microwave signal processing in the future, such as slow wave, fast wave, and radio-frequency memory. Our results indicate the HTS resonator is an ideal platform for investigating versatile coherent phenomena.
