Abstract

This paper designed a high sensitivity refractive index sensor based on two-dimensional square-lattice slow light photonic crystal waveguide. This structure based on Mach-Zehnder interferometer (MZI) which can be widely used in measuring the refractive index of liquid. The resolution of this sample structure can reach 7×10^-7 RIU. This kind of sensor can be integrated with electronic systems to measure the refractive index of gas or fluid.
