Loss Difference Induced Localization in a Non-Hermitian Honeycomb Photonic Lattice
Loss Difference Induced Localization in a Non-Hermitian Honeycomb Photonic Lattice
Non-Hermitian systems with complex-valued energy spectra provide an extraordinary platform for manipulating unconventional dynamics of light. Here, we demonstrate the localization of light in an instantaneously reconfigurable non-Hermitian honeycomb photonic lattice that is established in a coherently prepared atomic system. One set of the sublattices is optically modulated to introduce …
