Stabilization of light bullets in nonlinear metamaterial waveguides
A. K. Shafeeque Ali, A. Govindarajan, M. Lakshmanan
In this paper, we carry out a theoretical investigation on the propagation of spatio-temporal solitons (light bullets) in the nonlinear metamaterial waveguides. Our theoretical stu…
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…
Nondegenerate bright solitons in coupled nonlinear Schrödinger systems: Recent developments on optical vector solitons
S. Stalin, R. Ramakrishnan, M. Lakshmanan
Nonlinear dynamics of an optical pulse or a beam continue to be one of the active areas of research in the field of optical solitons. Especially, in multi-mode fibers or fiber arra…
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…
-channel comb filtering and lasing in -symmetric superstructures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
A comb spectrum generating device based on Bragg grating superstructures with gain and loss is suggested in this paper. It includes a comprehensive analysis of the device formulati…
