METHOD AND SYSTEM FOR UNIVERSAL CALIBRATION OF DEVICES UNDER TEST
Methods and systems include a universal, device-agnostic calibration process in which measured indications output by a device under test (DUT) (or corrected or converted indications derived therefrom) may be compared with calibration thresholds for any type of DUT to be calibrated. A complete, universal, and extensible calibration process is thus achieved that is capable of accommodating routine and complex calibration scenarios alike. A common set of statistics may be generated for all devices to be calibrated, without regard to the particular device under test, and statistics of the common set of statistics may be evaluated to determine the calibration state of the DUT. Additionally, the methods and systems disclosed herein provide for generating a comprehensive set of measurement records that may include some or all original observations, calculations, corrections, conversions, environmental factors, and measurement results, e.g., according to a standard, which allows for step-by-step auditing of every measurement performed.

A calibrator lead set, which electrically couples a first device and a second device during calibration of the second device, includes a cable having multiple wires, a first interface connector coupled to a first end of the wires of the cable, and a plurality of second interface connectors coupled to a second end of the wires that is opposite the first end of the wires. The first interface connector includes a connector retaining portion, multiple connection terminals extending from the connector retaining portion, and a sheath extending from the connector retaining portion and surrounding the connection terminals extending from the connector retaining portion. The sheath may be transparent to facilitate positioning of the connection terminals of the first interface connector. The second interface connectors may include a first sheathed, double banana plug connector and a second sheathed, double banana plug connector stackable on the first sheathed, double banana plug connector.
A photonic device has one or more optical resonators having a first resonant frequency response relative to temperature and a different second resonant frequency response relative to temperature. In at least one embodiment, a first waveguide optically couples input light having a first frequency to a first optical resonator and a second waveguide optically couples input light having a second frequency to a second optical resonator. Light output from the one or more optical resonators is combined. A temperature of the photonic device may be determined from a beat frequency in the combined light output. One or more photodetectors may convert the combined light output into an electric signal, and a detected frequency in the electric signal indicates the beat frequency of the combined light output. The beat frequency is correlated with a temperature of the photonic device. In an embodiment, one or more multimode optical resonators may be used.

TEMPERATURE MEASUREMENT SYSTEM AND METHOD USING OPTICAL SIGNAL TRANSMISSION THROUGH AN OPTICAL INTERFEROMETER
A temperature measurement technology includes generating an input optical signal at a wavelength using an optical signal generator, splitting the input optical signal into a first beam and a second beam, optically transmitting the first beam through the first arm of an interferometer, transmitting the second beam through a second arm of the interferometer that introduces a phase shift in the second beam relative to the first beam, combining at least a portion of the transmitted first beam and the transmitted phase-shifted second beam to produce an output optical signal, measuring an optical signal intensity of the output optical signal, and correlating the measured optical signal intensity with a temperature to produce a measured temperature. Alternatively, the input optical signal may be transmitted through two or more interferometers.

A photonic device has a substrate with one or more optical resonators having a first resonant frequency response relative to temperature and a different second resonant frequency response relative to temperature. A first waveguide optically couples a first light beam having a first frequency to a first optical resonator and a second waveguide optically couples a second light beam having a second frequency to a second optical resonator. An optical shifter may shift an optical characteristic of the second light beam. A detector converts output light from the photonic device into an electric signal having a characteristic indicative of a physical condition, such as temperature, of the photonic device. In some cases, output light from the one or more optical resonators is combined and a temperature of the photonic device is determined from a beat frequency in the combined light. One or more multimode optical resonators may be used.
