Abstract
In this work, we have optimized the performance of the 1D photonic crystal based biosensor. The photonic crystal contains the layers A, B and F which are ZnSe, SiO2 and a microfluidic channel, respectively. Also, there is a radial gradient refractive index defect layer in the center of the structure. By irradiating a plane beam to the proposed structure, a ring-shaped intensity profile is achieved on the output plane of the structure. Any changed in the effective refractive index of the fluid inside of microfluidic channels can cause a change in the radius of the intensity ring. There are different parameters such as number and thickness of the layers and the rate of the refractive index variation in the D layer that can effect the sensitivity. Optimizing these parameters, it is possible to sense the refractive index changes of 10^-5 .
