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…
Engineering Optical Rogue Waves and Breathers in a Coupled Nonlinear Schrödinger System with Four-Wave Mixing Effect
K. Sakkaravarthi, R. Babu Mareeswaran, T. Kanna
We consider a coherently coupled nonlinear Schrödinger equation with modulated self-phase modulation, cross-phase modulation, and four-wave mixing nonlinearities and varying refrac…
Manipulation of vector solitons in a system of inhomogeneous coherently coupled nonlinear Schrödinger models with variable nonlinearities
R. Babu Mareeswaran, K. Sakkaravarthi, T. Kanna
We investigate non-autonomous solitons in a general coherently coupled nonlinear Schrödinger (CCNLS) system with temporally modulated nonlinearities and with an external harmonic o…
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…
Spatially modulated two- and three-component Rabi-coupled Gross-Pitaevskii systems
T. Kanna, A. Annamalar Sheela, R. Babu Mareeswaran
Vector rogue wave (RW) formation and their dynamics in Rabi coupled two- and three-species Bose-Einstein condensates with spatially varying dispersion and nonlinearity are studied.…
Cubic-quintic nonlinear Helmholtz equation: Modulational instability, chirped elliptic and solitary waves
K. Tamilselvan, T. Kanna, A. Govindarajan
We study the formation and propagation of chirped elliptic and solitary waves in cubic-quintic nonlinear Helmholtz (CQNLH) equation. This system describes nonparaxial pulse propaga…
