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