FOURIER BASED COMBINED TECHNIQUES TO DESIGN NOVEL SUB-WAVELENGTH OPTICAL INTEGRATED DEVICES

We present a tool to aid the design of periodical structures, such as subwavelength grating (SWG) structures. It is based on the Fourier Eigenmode Expansion Method and includes the Floquet modes theory. Besides, the most interesting implemented functionalities to ease the design of photonic devices are detailed. The tool capabilities are shown using it to analyse and design {three} different SWG devices.
