Abstract
A thermometer system includes a photonic thermometer; and an optomechanical thermometer configured to calibrate the photonic thermometer, thereby making the thermometer system an optomechanically calibrated photonic thermometer.
Claims15
A nanophotonic thermometer system comprising:
- a photonic thermometer;
- and
- an optomechanical thermometer configured to calibrate the photonic thermometer, thereby making the thermometer system an optomechanically calibrated photonic thermometer.
A method of calibrating a nanophotonic thermometer system comprising:
- activating a temperature control device of the nanophotonic thermometer system;
- adjusting the temperature control device while iteratively measuring a relative temperature of the nanophotonic thermometer system until a photonic thermometer provides a fixed resonance frequency response;
- and
- measuring an absolute temperature of the nanophotonic thermometer system using an optomechanical thermometer;
- and
- calibrating the photonic thermometer using the absolute temperature measurement and a stable relative temperature measurement.

A method of operating a nanophotonic thermometer system comprising the steps of:
- operating the nanophotonic thermometer system in a process environment;
- measuring a relative temperature of a sample using a photonic thermometer of the nanophotonic thermometer system;
- measuring an absolute temperature of the sample using an optomechanical thermometer of the nanophotonic thermometer system;
- comparing the absolute temperature measurement and the relative temperature measurement;
- and
- if the measurements disagree, correcting the calibration of the photonic thermometer, and if the measurements agree, continuing operation without correction.
