Abstract: A sensor device comprises: a plurality of sensors, wherein each sensor comprises an optical resonance element configured to be affected by a measurand and has a mutually unique optical resonance frequency; the sensors being configured to receive at least one of a first and a second sensor interrogation signals forming a plurality of signal component pairs, wherein a difference in frequency between the frequencies in the signal component pair is different for different signal component pairs; wherein each sensor is configured to modulate an optical intensity of at least one frequency of a mutually unique signal component pair; and a detector, being configured to receive the first sensor interrogation signal and the second sensor interrogation signal, wherein the detector is configured to detect a plurality of mutually unique beat frequencies for detecting a plurality of measurements by the plurality of sensors.

Abstract: An optical frequency comb device includes: an optical waveguide; a first mirror disposed at a first position in the optical waveguide; a second mirror disposed at a second position different from the first position, in the optical waveguide; a gain medium and a saturable absorber which are disposed between the first mirror and the second mirror; and a controller that fixes one of a repetition frequency and a carrier-envelope offset frequency of an optical frequency comb output from an end of the optical waveguide, and changes the other of the repetition frequency and the carrier-envelope offset frequency.
