摘要

研究了具有二次非线性响应的波导阵列中的双色参数非线性模式。我们从理论上和实验上预测了在参数驱动的离散系统中，非线性晶格中的一种新型相变伴随着功率控制的交错模式结构的突变，这是由于局域化和同步化的相互作用。

Phase transitions of nonlinear waves in lithium niobate waveguide arrays

We study two-color parametric nonlinear modes in waveguide arrays with quadratic nonlinear response. We predict theoretically and observe experimentally a new type of phase transition in nonlinear lattices accompanied by an abrupt power-controlled change of the staggered mode structure due to an interplay of localization and synchronization in para-metrically driven discrete systems.
