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…

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}…
