Dynamics of Light Localization via Coherent Control: The Interplay of Transmission, Absorption and Disorder in Photonic Crystals
Nancy Ghangas, Ghanasyam Remesh, Venu Gopal Achanta +1
This study investigates the interplay between structural disorder, absorption, and Lyapunov exponent dynamics to exploit localization phenomena in photonic crystals with engineered…
Coherent control of nonreciprocal optical properties of the defect modes in 1D defective photonic crystals with atomic doping
Nancy Ghangas, Shubhrangshu Dasgupta
We investigate the spectral properties of photonic crystals, lacking parity-time (PT) symmetry, using scattering matrix formalism. We show using the symmetry properties of matrices…
Magneto-optical rotation of spectrally impure fields and its nonlinear dependence on optical density
G. S. Agarwal, Shubhrangshu Dasgupta
We calculate magneto-optical rptation of spectrally impure fileds in an optically thick cold atmic medium. We show that the spectral impurity leads to non-linear dependence of the…
