文章作者提出了一种实现多准位相匹配的一维光学超晶格的新的设计方法——自调整方法,详细介绍了用自调整方法设计非周期光学超晶格和无周期光学超晶格的流程,并对结果进行了分析.数值模拟结果表明,自调整方法是一种高效灵活的专用于设计一维光学超晶格的优化算法,与其他优化算法相比,自调整方法能在更短的时间内搜索出更理想的优化结果.此外,自调整方法的优化结果不依赖于参数的设置和初始化条件,运行方便.
A self-adjusting method for realizing multiple quasi-phase-matched nonlinear optical parametric processes in aperiodic and non-periodic optical superlattices is proposed. Numerical simulations show that this self-adjusting algorithm is more flexible and effective than other existing algorithms, and more ideal results can be gained in a much shorter time. In addition, it can avoid blind searching and is independent of the initial conditions.
