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…

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…

Tunable nonlinear spectra of anti-directional couplers

A. Govindarajan, Boris A. Malomed, M. Lakshmanan

We produce transmission and reflection spectra of the anti-directional coupler (ADC) composed of linearly-coupled positive- and negative-refractive-index arms, with intrinsic Kerr…

Tailoring inhomogeneous -symmetric fiber Bragg grating spectra

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

The unique spectral behavior exhibited by a class of non-uniform Bragg periodic structures, namely chirped and apodized fiber Bragg gratings (FBGs) influenced by parity and time re…
