Electromagnetically Induced Transparency in Planar Optical Waveguide

Atomic coherence is induced in the multilevel atomic system via strong control field that alters the response of medium to a weak probe laser field. This involves quantum interference in the amplitudes of optical transitions and causes the cancellation of absorption i.e. electromagnetically induced transparency (EIT). reducing the absorption via EIT can be employed to enhance the performance of waveguides that are extensively used in communication to transport electromagnetic waves from one point to another.
