Paper Abstract

We demonstrate uniform and sampled Bragg gratings in silicon-on-insulator ridge waveguides with slab-modulated sidewall corrugations. Coupling coefficient and bandwidth can be precisely controlled by varying the distance between the slab-sidewall corrugations and the ridge. A bandwidth of 3 nm at the center wavelength of 1550 nm for uniform Bragg gratings is achieved for 100 nm slab-sidewall corrugation. Based on this structure, sampled gratings with 0.4 nm bandwidth are proposed. The measured results show good agreement with theoretical analyses.
