Development of a novel FDTD algorithm and module for modelling nonlinear-optical effects**

非线性光学使得已经存在的波长可以产生不同波长的光。非线性光学存在于我们的日常活动中，它负责在市面上可获得的激光指示器中实现绿光发射，并且在许多医疗应用中都是必需的，尤其是健康行业。尽管这一领域在过去几十年里得到了大量新颖的研究，但其中大部分都是独立的实验数据，或者是结合非常简单的理论或数值模型的实验数据。为了使这一领域得到持续的发展，构建一种能够全面模拟这些非线性物理现象的新的计算算法是很重要的。这样的模型将允许研究人员预测不同实验情况的结果，使他们能够在进行任何昂贵的实验之前优化他们的设置。这将减少与进行实验相关的大量成本，允许调查更多种类的情况，并允许研究人员验证他们的实验观察。OptiWave Systems Inc.和艾伯塔大学的研究人员正在合作，目标是开发一种能够准确模拟非线性物理现象的新算法。通过向加拿大和国际客户提供这一新开发的产品，Optiwave将看到财务利益，加拿大将看到他们对新想法和新奇研究的重视得到越来越多的认可。**

Nonlinear optics allows different wavelengths of light to be generated from already existing wavelengths. Nonlinear optics is present in our daily activities, where it is responsible for achieving green-light emission in commercially available laser pointers and is required in numerous medical applications paramount to the health industry. Although this area has received a surge of novel research over the past few decades, much of it is stand-alone experimental data or experimental data in conjunction with very simple theoretical or numerical models. For this area to experience continued development, it is important to construct a novel computational algorithm having the ability to comprehensively model these nonlinear physical phenomena. Such a model would allow researchers to predict the outcome of different experimental situations, allowing them to optimize their setup prior to performing any expensive experiments. This would reduce the substantial costs associated with performing experiments, allow a larger variety of situations to be investigated, and allow the researchers to verify their experimental observations. Optiwave Systems Inc. and researchers from the University of Alberta are collaborating with the objective of developing a novel algorithm capable of accurately modelling nonlinear physical phenomenon. By offering this newly developed product to Canadian and international customers, Optiwave will see financial benefits and Canada will observe increased acknowledgment for their emphasis on new ideas and novel research.**
