Induced transparency by interference or polarization
Abstract
Electromagnetically induced transparency (EIT) describes the phenomenon that an opaque optical medium becomes transparent due to interference effects. EIT plays a pivotal role in engineering slow light and quantum memory. However, polarization effects could cause similar phenomena and therefore were considered as EIT occasionally. We investigate the polarization effects on EIT in optical resonators and discover a polarization-induced transparency (PIT) phenomenon that the system is transparent in one direction but opaque in the other. PIT results from the polarization effects rather than wave interference and thus fundamentally differs from EIT. This study resolves the confusion between EIT and polarization effects, which is crucial for optical memory design and paves the way to additional techniques for controlling wave propagation.
