Multistability and Switching in Oppositely Directed Saturable Coupler
K. Nithyanandan, A. K. Shafeeque Ali, M. P. M. Nishad +3
We report a novel optical multistability in two core oppositely directed saturable coupler (ODSC) with negative index material (NIM) channel. The dynamics are studied using the Lan…
Ultrashort dark solitons interactions and nonlinear tunneling in the modified nonlinear Schrödinger equation with variable coefficients
N. M. Musammil, K. Porsezian, K. Nithyanandan +2
We present the study of the dark soliton dynamics in an inhomogenous fiber by means of a variable coefficient modified nonlinear Schrödinger equation (Vc-MNLSE) with distributed di…
Rogue wave triggered at a critical frequency of a nonlinear resonant medium
Jingsong He, Shuwei Xu, K. Porsezian +2
We consider a two-level atomic system, interacting with an electromagnetic field controlled in amplitude and frequency by a high intensity laser. We show that the amplitude of the…
Shape changing (intensity redistribution) collisions of solitons in mixed coupled nonlinear Schr{ö}dinger equations
T. Kanna, M. Lakshmanan, P. Tchofo Dinda +1
A novel kind of shape changing (intensity redistribution) collision with potential application to signal amplification is identified in the integrable -coupled nonlinear Schr{ö}…
