A novel design of one dimensional annular photonic crystals with a low birefringence nematic liquid crystal as a defect layer is introduced. The output field of the sensor structure is plotted after different optimization steps on all constituents such as thickness and core radius of the starting medium. The performance of the sensor was studied using different quality parameters such as sensitivity, figure of merit, detection limit and resolution. The designed sensor exhibits a sensitivity of about 0.224 nm °C −1 due to the presence of the liquid crystal material. The proposed sensor design can be used as a narrowband optical filter in the visible region around two wavelengths: 600 nm and 700 nm. As an optoelectronic device, this structure can serve as a temperature sensor with higher sensitivity than the conventional one dimensional photonic crystal structures and photonic crystals fibers.

向列型液晶增强环形一维光子晶体温度传感器的灵敏度

介绍了一种以低双折射向列液晶为缺陷层的一维环形光子晶体的新颖设计。在不同的优化步骤之后，在所有成分（例如起始介质的厚度和芯半径）上绘制传感器结构的输出场。使用不同的质量参数（例如灵敏度，品质因数，检测极限和分辨率）研究了传感器的性能。由于存在液晶材料，因此设计的传感器表现出约0.224 nm°C -1的灵敏度。所提出的传感器设计可用作在两个波长（600 nm和700 nm）附近的可见光区域中的窄带滤光片。作为光电设备，
