本计画所提出的方法是一种非常有前途且通用的方法，可以在高折射率材料中实现三维非线性光子晶体。该项目将扩大非线性光子晶体领域的国家知识。球面像差的成功补偿将推动光学微细加工技术的发展。预计该项目将为研究生提供许多参与的机会。一些新开发的基于非线性光子晶体的器件可能会找到它们的商业应用，我们有机会保护与这些应用相关的知识产权。从长远来看，非线性光子晶体在日常生活中有着广泛的应用，并为工业界提供了发展的机会。

The method proposed in this project is a very promising and versatile method to achieve 3D nonlinear PhCs in a high refractive index material. This project will expand the national knowledge in the area of nonlinear PhCs. The successful compensation of the spherical aberration will advance the optical microfabrication technique. It is expected that the project will provide many chances for postgraduate students to become involved. Some newly developed devices based on nonlinear PhCs may find their commercial applications and we have a chance of securing the intellectual property related to these applications. In a long term, nonlinear PCs may be widely used in daily life and provide some opportunities to the industries.
