Effects of the linear mismatch and nonlinear asymmetry in the nonlinear coupler

摘要: Two types of nonlinear couplers exhibit identical coupling behaviors if their corresponding characteristic parameters and linear mismatches are equal values but opposite signs. Complete power transfer can be attained in a coupler when parameters, mismatch the input satisfy an equation. For asymmetrical coupler, only one lead to complete transfer. It leads some new applications coupler. The conditions for stable unstable equilibrium presented, they depend on asymmetry mismatch. impact switching characteristics is discussed. slight or shifted by means varying symmetry while features remain nearly unchanged. operation counteracted nonlinearity. When high, exhibits good limiting not characteristics.
