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…
Reviving Modulational Instability with Third-Order Dispersion
K. Tamilselvan, A. Govindarajan, T. Kanna +2
It is well-known that third-order dispersion (TOD) never allows the continuous wave of any nonlinear Schroedinger (NLS) type system to experience modulational instability (MI). Rem…
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…
