The advantage for quadratic soliton generation of engineering the quasi-phase-matching period near the input of lithium niobate slab waveguides is demonstrated. This approach allows members of one-dimensional quadratic soliton families with different values of the wave-vector mismatch to be cleanly excited and to be characterized by quantitative intensity-profile measurements of both the fundamental and the second-harmonic soliton components.
研究表明，在铌酸锂平板波导输入端附近设计准相位匹配周期对于二次孤子产生具有优势。这种方法能够清晰地激发具有不同波矢失配值的一维二次孤子族成员，并通过对基波和二次谐波孤子分量进行定量强度分布测量来对其进行表征。
