摘要:

电阻测温法是一种经过时间考验的温度测量方法。近年来,基于电阻的方法的基本限制激发了人们对开发光子温度传感器作为可行的替代方案的极大兴趣。在这项研究中,我们证明了我们的光子温度计,它由一个集成了布拉格光栅的硅波导组成,可用于测量温度变化范围从5 C到160 C的综合扩展不确定度[k = 2 ; 95%置信水平]为1.25摄氏度。传感器的计算模型预测的谐振波长和有效折射率的测量值的4%以内。

英文摘要:

Resistance thermometry is a time-tested method for taking temperature measurements. In recent years fundamental limits to resistance-based approaches spurred considerable interest in developing photonic temperature sensors as a viable alternative. In this study we demonstrate that our photonic thermometer, which consists of a silicon waveguide integrated with a Bragg grating, can be used to measure temperature changes over the range from 5 C to 160 C with a combined expanded uncertainty [k = 2 ; 95% confidence level] of 1.25 degree C. The computational modeling of the sensor predicts the resonance wavelength and effective refractive index within 4% of the measured value.
