An isotropic medium, having magnetic sublevels, when subjected to a magnetic field or an electromagnetic field can induce anisotropy in the medium; and as a result the plane of polarization of the probe field can rotate. Therefore the rotation due to the magnetic field alone, can be controlled efficiently with use of a coherent field. We show, using a control field, significant enhancement of the magneto-optical rotation and demonstrate the possibility of realizing magneto-optical switch.

Coherent Control of the Polarization of an Optical Field
Through use of quantum coherence in an atomic system, we demonstrate that an optical field can be used to completely control the polarization state of another field. Theoretical and experimental
Resonantly enhanced refractive index without absorption via atomic coherence.
An enhancement of the index of refraction accompanied by vanishing absorption is shown to be possible is an ensemble of phase-coherent atoms (phaseonium), and the influence of processes such as Doppler broadening that degrade coherence is discussed.
