Analysis of subwavelength - grating waveguide structures with 3D Fourier modal methods

Popis výsledku v původním jazyce

Very high-contrast waveguide components, especially those based on silicon-on insulator (SOI) platform, are very perspective due to their small dimensions and strongly reduced bending loss, which allows for larger scale photonic integration. Nowadays, not only passive but also "dynamic", externally controllable devices as, e.g., fast modulators and even photodetectors have been developed. Although the very high refractive contrast of SOI platform appears very useful in these aspects, it is too high forsome others. This disadvantage can be removed in a very elegant way - by segmenting the silicon waveguide into sections of a subwavelength size that are embedded into a low-index environment such as SiO2 or SU-8 photoresist. By changing the "Si filling fraction" of such a subwavelength grating waveguide (SWG), its "average" refractive index can be tuned essentially to any value between that of silicon and silicon dioxide in accordance with the effective medium theory. However, in order t
