VirtualLab Fusion training: Analysis and Design of Diffractive and Micro-Optical Systems
Attendees at the software course develop their skills in modeling and analysis of micro-structured and diffractive optical components with refractive, diffractive and hybrid surfaces. Customized surface profiles and refractive index distributions will also be explained. The course teaches the analysis of these components including diffraction and interference effects. The modeling and analysis of typical tolerances, e.g. of micro-structured elements, will be discussed along several examples. We present the optimization of diffractive beam splitters, diffusers and beam shapers by the Iterative Fourier Transform Algorithm (IFTA). The course will also cover the use of the Fourier Modal Method (FMM) to model and perform a rigorous analysis of both 2D and 3D grating structures with features in the wavelength range and with arbitrary surface and index modulations. Finally local and global parametric optimization algorithms of VirtualLab for the rigorous optimization of gratings will be introduced.
