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 …

The influence of Kerr nonlinearity and Doppler broadening on the slow light propagation of a

We present theory to describe an engineering dispersion technique to obtain a broadband
effective index near zero with an asymmetric planar photonic crystal. The theory provides the …

The idea of optical photonic crystal, which is generated using two counter-propagating
fields, is revisited to study gain-assisted all-optical switch and diode using Kerr field. Two …
