An ultra-high sensitive sensor over a wide range of temperatures based on the optical Tamm resonance and the pyroelectric effect is presented. The lithium niobate (LN) material is considered in a one-dimensional photonic crystal (1D-PC) for such purpose. The sensing process is based on the displacement of the optical Tamm plasmon (TP) resonance in the near-infrared (NIR) region. All parameters were optimized to produce the highest performance. The numerical results are validated by using the transfer matrix method (TMM). We obtained a sensitivity of 1.10 nm/K in a wide range of temperatures from 300 K to 700 K, which is higher than many reported 1D-PC temperature sensors. The high sensitivity is due to the pyroelectric effect of the LN material, which causes the refractive index to increase significantly with temperature changes. The proposed sensor design may be of great interest to optoelectronics and temperature sensor applications.

提出了一种基于光学Tamm共振和热释电效应的宽温度范围内的超高灵敏度传感器。为此目的，在一维光子晶体（1D-PC）中考虑了铌酸锂（LN）材料。感测过程基于光学Tamm等离子体激元（TP）共振在近红外（NIR）区域中的位移。所有参数均经过优化以产生最高性能。通过使用传递矩阵方法（TMM）验证了数值结果。我们在300 K至700 K的宽温度范围内获得了1.10 nm / K的灵敏度，这比许多报道的1D-PC温度传感器要高。高灵敏度归因于LN材料的热电效应，这会导致折射率随温度变化而显着增加。
