Simulation of Optical and Photonic Systems

Waveguide and Thin Film Simulation

Numerical methods and modelling techniques are gaining importance in the design of optical systems. We are particularly interested in the modelling of optical thin films.

Thin Film Simulation (FilmStar)

The calculation and modelling of reflective and transmissive properties of thin film systems are based on the Fresnel equations. With the use of matrix algorithms the spectral performance at various incident angles can be calculated. One can even determine the associated colour to the spectrum in the CIE colour space. The TFCalc software package is used to model of anti-reflective, mirror or filter coatings. For more complex tasks like optimization or the analysis of existing spectral curves we use the software package Filmstar by FTG.
