Unique multistable states in periodic structures with saturable nonlinearity

S. Vignesh Raja, A. Govindarajan, M. Lakshmanan

We report that conventional saturable periodic structures, in sharp contrast to the conventional systems with different nonlinearities which exhibit the typical S- shaped optical b…

Low-power optical bistability in -symmetric chirped Bragg gratings with four-wave mixing

S. Sudhakar, S. Vignesh Raja, A. Govindarajan +2

The central theme of this article is the analysis of the usefulness of introducing four-wave mixing or modulation of Kerr nonlinearity in a nonuniform grating structure with gain a…

Modulation instability induced supercontinuum generation in liquid core suspended photonic crystal fiber with cubic-quintic nonlinearities

A. Sharafali, A. K. Shafeeque Ali, M. Lakshmanan

In this paper, we propose a liquid core suspended photonic crystal fiber (LCSPCF) as a potential waveguide structure for nonlinear applications. We emphasize the dramatic improveme…

Dispersion Managed Generation of Peregrine Solitons and Kuznetsov-Ma Breather in an Optical Fiber

Dipti Kanika Mahato, A. Govindarajan, M. Lakshmanan +1

Optical rogue waves and its variants have been studied quite extensively in the context of optical fiber in recent years. It has been realized that dispersion management in optical…

Phase shifted -symmetric periodic structures

S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1

We report the spectral features of a phase-shifted parity and time ()-symmetric fiber Bragg grating (PPTFBG) and demonstrate its functionality as a demultiplexer in t…
