DESCRIPTION: \n\nAbstract\n\nSilicon photonics (SiP) is an emerging techniq
 ue that can enable compact photonic integrated devices with the high perfo
 rmance. Over the decades\, numerous active and passive devices have been w
 ell developed\, e.g.\, modulators\, optical micro-ring resonators\, wavegu
 ide Bragg gratings (WBGs)\, and photodetectors. Recently\, subwavelength g
 rating (SWG) has attracted lots of attentions due to its lower propagation
  loss\, the flexibility in tailoring effective indices\, and the unique fe
 ature in manipulating the polarization. Various SWG waveguide-based SiP de
 vices have been demonstrated\, such as the SWG WBGs\, SWG micro-ring reson
 ators\, SWG based crossings\, and SWG assisted contra-directional couplers
 \, etc. Thanks to the characteristics of the SWG structure\, the performan
 ce of these photonic integrated devices has been largely improved. In this
  thesis\, we aim to improve the performance of WBGs by using SWG structure
 s. Several SWG WBG structures are developed and experimentally demonstrate
 d in three categories: 1) the management of the group delay\; 2) the manag
 ement of resonances\; 3) the management of the polarization.\n
