Abstract
A temperature measurement system includes an optical resonator, a detector, and a computing subsystem. Light resonates in the optical resonator at resonant wavelengths that vary relative to a temperature in the optical resonator. The detector detects at least two resonant wavelengths of light output from the optical resonator. The computing subsystem determines the temperature of the optical resonator based at least in part on a mathematical operation on the at least two resonant wavelengths of the light output from the optical resonator. The mathematical operation may be a subtraction operation that determines a wavelength difference between two resonant wavelengths. In various implementations, the temperature of the optical resonator is determined based on a mapping of the wavelength difference to the temperature or based on an identified mode of the optical resonator and a mapping of the resonant wavelength to the temperature of the optical resonator in the mode.
