We propose a model to manipulate group velocity of a multi-frequency probe light in an
electromagnetically induced transparency medium consisting of five-level cascade-type …

The advent of electromagnetically induced transparency (EIT) offered a new coherent
material with exotic and controllable optical properties. Although, studies on single-EIT are …

We study the nonlinear optical properties of graphene to explore the Faraday rotation (FR) of
a terahertz light pulse propagating through its anisotropic pattern. The weak light's FR angle …

We propose a tunneling-induced grating based on the phenomenon of tunneling-induced
transparency. Our method allows us to alternate between zeroth-order diffraction along with …

We study slow and fast light propagation through a static magnetic field at room temperature
in a degenerate four-level atomic medium. The probe field absorption spectrum and group …

We study the electromagnetically induced grating in a four-level N-type atomic system in the
presence of Kerr field, spontaneously generated coherence (SGC), and Doppler …

We have achieved a negative refractive index with significantly reduced absorption in a
three-level Λ-type atomic gas medium under Doppler broadening. It shows that the …

A four-level double lambda closed atomic configuration is considered to study the
polarization plane rotation of the probe beam through cold as well as thermal Rb 87 atomic …

A four-level N-type atomic medium is considered to study the effect of spontaneous
generated coherence (SGC) and Kerr nonlinearity on light pulse propagation. A light pulse …

The optical response of a magnetic-degenerated four-level atom system to the two left and
right circular polarization components of the probe field is represented at room temperature …
