▲ [20a-211B-8] Multistability in directional coupler with negative index material channel
キーワード：Nonlinear Optics
We observe optical mulistability in opposite directly coupler (ODC) with negative index material channel. The emergence of multiple stable states is a result of combined action of nonlinear saturation and opposite directionality of phase velocity and energy flow in the ODC.
