Query: On-Chip Silicon Waveguide Bragg Grating Photonic Temperature Sensor   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.
