The radiation spectrum method: a next-generation computational tool for photonics

The Radiation Spectrum Method (RSM) is a fast an accurate computational approach for modeling how light propagates in integrated photonic components. Unlike traditional beam propagation techniques, RSM uses a modal description of light instead of numerical grids, reducing computation time while improving physical insight. The method represents complex optical structures as a sequence of simple waveguide segments and efficiently calculates light coupling, reflection, and polarization effects. By combining high precision with fast Fourier transform, RSM provides a powerful tool for the design and optimization of advanced photonic devices in modern computational optics. We will give several results and in particular the last open source usable on MacOS or Windows available at this link on sourceforge: https://sourceforge.net/projects/rsmvisit/.
