A thermometer includes a substrate; an optical resonator disposed on the substrate and including an optical resonance, the optical resonator being configured to receive a resonant frequency corresponding to the optical resonance; and a waveguide disposed on the substrate proximate to the optical resonator to receive input light, to communicate the resonant frequency to the optical resonator, and to transmit output light; wherein an aperture is interposed between: the substrate and the optical resonator, the substrate and the waveguide, or a combination comprising at least one of the foregoing, and the thermometer is configured to change the optical resonance in response to a change in temperature of the optical resonator.

Optical temperature sensor and use of same

An article to determine a sample condition includes a substrate; a reference optical cavity disposed on the substrate and comprising a reference cavity, the reference optical cavity being configured to support a reference optical resonance and to maintain an axial length of the reference cavity; and a sample optical cavity disposed on the substrate and comprising a sample cavity, the sample optical cavity being configured to support a sample optical resonance and to maintain an axial length of the sample cavity.

Photonic article, process for making and using same

A thermometer is provided. A housing has at least one opening. A dielectric element is disposed in the housing. At least one microwave guide is coupled to the at least one opening for providing a signal into the dielectric element for propagation at a resonant frequency and for receiving the signal from the dielectric element. A temperature determination unit receives the signal from the at least one microwave guide, measures the resonant frequency of the dielectric element, and determines the temperature of the dielectric element based on a relationship between resonant frequency and temperature of the dielectric element.
