NM13-Highly sensitive ring resonator based refractive index sensor for label free biosensing applications

Ring resonator based label free refractive index biosensor is proposed for detecting glucose and hemoglobin concentrations. To improve device sensitivity and Q factor, various parameters of ring resonator are optimized. The designed ring resonator sensor can sense hemoglobin and glucose concentrations with a high sensitivity of 424 nm/RIU and Q factor of 802.
