We study the optical bistability and multistability in a defect structure doped with polaritonic
materials and three-level nanoparticles. It is realized that the threshold of optical bistability …

The optical bistability and multistability properties are studied in a defect slab doped with
acceptor and donor quantum dots embedded in a nonlinear photonic crystal. It is shown that …

In this paper simulation and mathematical analysis is done for ultra short optical pulses
which are generally used in signal transmission. A mathematical theory is provided to show …

The dispersion plays an important role in pulse propagation in an optical fiber. The effect of
higher order dispersion terms are generally neglected for pico second pulse propagation. In …

Ultra fast pulse evolution in a semiconductor quantum well structure (QWS) is theoretically
analyzed using split-step Fourier method. The induced polarization in the medium has been …
