Abstract

In this study, a one-dimensional mirror photonic crystal sensing model with GaN and AlN arranged alternately was designed to measure the concentration of NaCl solution using the transmission matrix method. The model is less affected by the ambient temperature, and the sensitivity reaches 1002 nm/RIU with a quality factor of 1990. In addition, the effects of the photonic crystal period number and the angle of incidence on the model are also investigated.
