Unique multistable states in periodic structures with saturable nonlinearity. II. Broken -symmetric regime
S. Vignesh Raja, A. Govindarajan, M. Lakshmanan
In this work, we observe that the -symmetric fiber Bragg gratings (PTFBGs) with saturable nonlinearity (SNL) exhibit ramp-like, mixed, optical multistability (OM) in…

Inhomogeneous nonlinearity meets -symmetric Bragg structures: Route to ultra-low power steering and peculiar stable states
S. Sudhakar, S. Vignesh Raja, A. Govindarajan +2
In the context of -symmetric fiber Bragg gratings, tailoring the nonlinear profile along the propagation coordinate serves to be a new direction for realizing low-pow…
