Abstract
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.
