摘要

几年前，在体晶体(2D)和平面波导(1D)的二次谐波产生过程中，二次孤子被观测到[1,2]。它们由强耦合的基场和谐波场组成，由于级联非线性和SHG固有的强光束间耦合的结合，它们在空间中锁定在一起传播而没有衍射。

One-dimensional quadratic walking solitons in lithium niobate planar waveguides

Quadratic solitons were observed a few years ago during second harmonic generation in both bulk crystals (2D) and planar waveguides (1D)[1,2]. They consist of strongly coupled fundamental and harmonic fields which propagate locked together in space without diffraction due to a combination of the cascaded nonlinearity and the strong inter-beam coupling inherent in SHG.
