The sidewalls of the rib and the slab are corrugated using different periods, resulting in two Bragg wavelengths that are controlled separately.}, keywords = {Bragg grating, multi-period, silicon photonics, rib waveguide}, URL = {http://dx.doi.org/10.1109/IPCon.2013.6656627}, author = {Xu Wang and Han Yun and Nicolas A.
