Abstract: A sensor structure for an acoustical pressure sensor. The structure comprises an optical waveguide closed-loop resonator and a plurality of sensor elements, wherein the individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. Further, the optical waveguide closed-loop resonator is arranged at said plurality of sensor elements and associated with each of the individual sensor elements of the plurality of sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements of the plurality of sensor elements.
