Essentials for silicon photonics are lowering size and cost without affecting effectiveness for various performances. One of the effective sensing elements with smaller footprints and few step fabrication is a micro ring resonators (MRR). Slotted waveguides and sub-wavelength gratings (SWG) have also shown higher sensitivity. Recently these combination of SWG and slotted waveguides exhibited even higher performances. In the study, we propose a sensor with slotted SWGs on a straight waveguide where Bragg grating (BG) reflection condition is fulfilled.
