文摘

Electromagnetically induced transparency is a phenomenon that drastically alters light-matter interactions such that an optically opaque medium becomes transparent. To date, it is widely accepted that broken symmetry is a necessary and sufficient condition for the realization of electromagnetically induced transparency (EIT) in nano-plasmonic structures. We have confirmed that even without broken symmetry, the plasmonically induced transparency (PIT) effect based on excitation of magnetic plasmon resonance can be created. We also demonstrated that in general, in the system allowing for higher-order mode excitation, broken symmetry may not be a sufficient condition for the realization of the EIT, in that the EIT may disappear even if the symmetry is broken.
