High Quality Silicon Photonics Optical Ring Resonator Biosensor Design

Abstract

This paper presents a high quality biosensor based on silicon photonics optical ring resonator for breast cancer detection. The sensor function by detecting the changes in interaction between light circulating inside the sensor and matter, which is antibody used for breast cancer on the sensor surface. The performance of optical ring resonator is investigate from the sensing point of view by measuring the change in resonance wavelength of ring resonator due to the change in refractive index. We reciprocate the process of binding of breast cancer antibody with respective antigen by changing the radius of ring resonator in simulations.
