A micron-range displacement sensor based on thermo-optically tuned whispering gallery modes in a microcapillary resonator

HIGHLIGHTS

  • who: Zhe Wang and colleagues from the Photonics Research Centre, School of Electrical and Electronic Engineering, Technological University, Newcastle upon Tyne , ST, UK have published the paper: A Micron-Range Displacement Sensor Based on Thermo-Optically Tuned Whispering Gallery Modes in a Microcapillary Resonator, in the Journal: Sensors 2022, 8312 of /2022/
  • what: The authors show that the above structure can be utilized as a displacement sensor with high sensitivity of 15.44 pm/u00b5m in the displacement range of 200 u00b5m. To confirm the results of the experiment in Figure 3a, another simulation was . . .
