Abstract : An optimal design method for low-order periodic dielectric diffractive structures in E-parallel polarization has been developed. A key property of the method is that nonsmooth design profiles present no theoretical or practical difficulties so that manufacturable designs can be achieved. The method is based on an accurate partial differential equation diffraction model. It has been theoretically justified, implemented, and applied to reveal some unexpected high-efficiency diffractive structures for potential use in photonic and micro-optical devices. Research associated with the development of the method has led to efficient numerical methods for calculating diffraction through grating structures and improved understanding of total variation methods for image processing and inverse problems, and has established the groundwork for three-dimensional design methods.
