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

非线性光学允许从已经存在的波长产生不同波长的光。非线性光学存在于我们的日常活动中，它负责实现商用激光笔的绿光发射，并且在许多医疗应用中都需要对健康行业至关重要。尽管在过去的几十年里，这一领域的新研究激增，但其中大部分是独立的实验数据或与非常简单的理论或数值模型相结合的实验数据。为了使这一领域得到持续发展，构建一种能够全面模拟这些非线性物理现象的新型计算算法是很重要的。这样的模型将使研究人员能够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结果。Optiwave系统公司和阿尔伯塔大学的研究人员正在合作开发一种能够精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种新开发的产品，Optiwave将获得经济效益，加拿大将因其对新思想和新研究的重视而得到更多的认可

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.**
