Nonlinear nonuniform -symmetric Bragg grating structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We explore the consequences of incorporating parity and time reversal () symmetries on the dynamics of nonreciprocal light propagation exhibited by a class of nonunif…

Multifaceted dynamics and gap solitons in -symmetric periodic structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We report the role of -symmetry in switching characteristics of a highly nonlinear fiber Bragg grating (FBG) with cubic-quintic-septic nonlinearities. We demonstrate…

Nonlinear anti-directional couplers with gain and loss
A. Govindarajan, Boris A. Malomed, M. Lakshmanan
Following the concept of -symmetric couplers, we propose a linearly coupled system of nonlinear waveguides, made of positive- and negative-index materials, which carr…
