Switching and enhanced bistability in an asymmetric nonlinear directional coupler with a metamaterial channel

► Switching in a nonlinear coupler with a metamaterial channel is studied. ► The coupler has one conventional channel with a decreasing Kerr nonlinearity. ► Bistability can be optimized by tuning the decrease rate of the nonlinearity. We numerically simulate the propagation and switching of ultra-sh...
