Subwavelength Grating Double Slot Waveguide Racetrack Ring Resonator for Refractive Index Sensing Application
In this paper, a racetrack ring resonator design based on a subwavelength grating double slot waveguide is presented. The proposed waveguide scheme is capable of confining the transverse electric field in the slots and the gaps between the grating segments. This configuration facilitates a large lig...
