In this paper, we investigated slow light to increase sensitivity and quality factor of our recently designed bio-sensors. A finite difference time domain and Plane Wave Expansion methods are employed to figure out sensors’ performances. We proposed slow light based photonic crystal structures with elliptical cells and we obtained higher sensitivity and quality factor as previously reported. For the first proposed sensor, the results showed that quality factor increased from 570 to 723 and a detection limit below 10−3. For the second sensor, the sensitivity increased from 550 to 650 nm/RIU and the detection limit is around 10−3. These two proposed structures would offer great potential for novel compact biosensors in medical application.
