Resources

Nanocomp has wide resources available for diffractive optics design. Our staff includes several diffractive optics experts with over a decade of experience in the field and boasts six doctoral degrees in optics. Nanocomp’s design tools include widely-used Matlab and Zemax, which both enable modern design methods. Lengthy experience has generated a library of ready-to-use codes and a wide range of case studies.

Design Methods

Rigorous analysis of micro-optical components needs the exact solutions of Maxwell’s equations and electromagnetic boundary conditions. The Fourier modal method – FMM - is a versatile approach to model twodimensional gratings but it can also be extended to three-dimensionally modulated structures or structures with non-binary profiles. Approximate methods are simple and fast approaches to analyze grating diffraction problems.

The iterative Fourier transform algorithm is one of the most popular methods for designing thin diffractive optical elements in the paraxial domain.

Structure optimization of various types of parameters is a classical problem in micro-optics. A typical task in the design of a micro structure is to find a suitable profile shape. Parametric optimization enables us to design structures for which the fabrication tolerances and limitations can be easily considered.
