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…
On the integrability aspects of nonparaxial nonlinear Schrödinger equation and the dynamics of solitary waves
K. Tamilselvan, T. Kanna, A. Govindarajan
The integrability nature of a nonparaxial nonlinear Schrödinger (NNLS) equation, describing the propagation of ultra-broad nonparaxial beams in a planar optical waveguide, is studi…
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…
