Rigorous Analysis of Resonant Waveguide Gratings
Time: 2020-01-18 18:31Source: δ֪Writer: infocrops
Resonant waveguide gratings (RWG), due to their tunability in e.g. wavelength, phase, and polarization, are applied in research and industry for various purposes. The structure of an RWG contains a thin high-refractive-index waveguide film that is in contact with a grating. The waveguide supports several guided modes, and, depending on the thickness, the number of modes varies. In this example, we apply the Fourier modal method (FMM) within VirtualLab Fusion to analyze the property of RWG rigorously.
