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…
Polarization dynamics of ultrafast solitons
Avi Klein, Sara Meir, Hamootal Duadi +2
We study the polarization dynamics of ultrafast solitons in mode-locked fiber lasers. We find that when a stable soliton is generated, it's state-of-polarization shifts toward a st…
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…
Modulational instability in non-Kerr photonic Lieb lattice with metamaterials
A. K. Shafeeque Ali, Andrei I. Maimistov, K. Porsezian +2
We present an analysis of modulational instability of diffractionless waves in a face-centered square lattice of waveguides featuring non-Kerr nonlinearity, which are constituted b…
