Abstract
This research demonstrates a high-performance temperature sensor based on the one-dimensional photonic crystal. The main idea of our sensing procedure is essentially depending on the pyroelectric effect, Tamm plasmon resonance, and Fano resonance. The designed sensor is configured as prism/Au/[LiNbO3/air](N)/SiO2. The inclusion of a thin layer of Au leads to the appearance of Tamm and Fano resonances. The novel thermal characteristics of LiNbO3 could have a significant effect on the position of these resonant modes. Thus, the shift in the position of the resonant mode due to temperature variations plays a fundamental role in the sensing process. The numerical results were performed based on the optimization procedure of the different parameters to investigate the highest possible performance. Therefore, the optimized sensor provides a higher sensitivity (3.035 nm/K) than many previously reported data.
