Abstract
Resistance thermometry is a time-tested method for temperature measurements. Fundamental limits to resistance-based approaches, spurred our interest in developing photonic temperature sensors as a viable alternative. In this study we demonstrate that our 1st generation photonic thermometer consisted 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 uncertainty [k = 2 ] of 1.25 C. The computational modeling of the sensor predicts the resonance wavelength and effective refractive index within 4% of the measured value. .Citation
