Silicon dumbbell-shaped micro-ring resonator for glucose monitoring

Abstract The use of a newly designed silicon dumbbell-shaped micro-ring resonator-based device was conceptualised for sensing applications. In particular, an illustrative example of glucose monitoring was presented considering various values of its concentrations in deionized water. The device operates on the principle of field coupling in integrated optic circuits. To be more specific, the configuration incorporates a specially designed silicon micro-ring resonator placed in the proximity of a straight optical waveguide, which serves as the input and output ports for the optical power. The values of quality factor and time delay were determined in the absence/presence of measurands of different concentrations. The results reveal the specially configured optical waveguide design to be highly sensitive for glucose monitoring applications.
