VirtualLab Fusion Technology and Applications

Gratings and Diffractive Lenses

12 – 13 February 2020
Premiere Workspaces, San Jose, CA, USA
9:00 – 17:00

Gratings, metagratings, and diffractive lenses are increasingly gaining importance in modern optics for various purposes. Subwavelength structures including metasurface building blocks extend the potential of microand nanostructured flat optical components. Naturally, modeling and design of such components and their inclusion in optical systems require physical-optics techniques. We show how VirtualLab Fusion provides you with the technologies and tools you need.

Learning outcomes:

  • Gain an overview of different applications of diffractive optics including: gratings for spectrum separation, lightguide coupling and polarization manipulation, metagratings with high efficiency, diffractive lenses in imaging, point-cloud generation, and more.
  • Understand the theory and usage of modeling technologies for gratings and diffractive lenses: the Thin Element Approximation (TEA), the Local Plane Interface Approximation (LPIA), and the rigorous Fourier Modal Method (FMM), also known as RCWA.
  • Practice hands-on with workflows in VirtualLab Fusion for the modeling and design of various types of gratings, including blazed, binary (also slanted), holographic, and metagratings for different applications. Analysis of whole optical systems which include gratings and diffractive lenses.
