Special Issue Information

Dear Colleagues,

The interest in the development and practical implementation of integrated and fiber optic sensors for the measurement of electromagnetic fields has led to the commercialization of a number of earlier proposed solutions. During recent years, we have witnessed new developments and a growing interest in novel approaches in this area—more specifically, the development of micro-interferometers or other optical waveguide structures in combination with magnetic fluids or magnetostrictive materials, the use of specialty optical fibers and the application of optical fiber sensors for the detection of electric discharges.

The objective of this Special Issue is to present the latest research and practical applications of integrated and optical fiber magnetic and electric field sensors: new approaches, the use of advanced technologies, materials, specialty fibers, interrogation and multiplexing techniques, reliability issues and manufacturability.

Potential topics include, but are not limited to:

  • Intrinsic and extrinsic magnetic field/electric current and electric field/voltage sensors;
  • Polarimetric, interferometric and refractometric intensity and wavelength-dependent interrogation schemes;
  • Magnetic field/current sensors based on magnetostrictive, magneto-optic materials and magnetic fluids;
  • Electric field/voltage sensors based on electro-optic materials and liquid crystals;
  • Sensing platforms for extrinsic sensors: FBGs, LPGs, plasmonic, intermodal interferometers, uIMZI, taper, Fabry Perot;
  • Specialty optical fibers for magnetic and electric field sensing applications;
  • Interrogation and multiplexing techniques for optical magnetic and electrical field sensors;
  • Detection of current short circuit and voltage breakdown or discharges;
  • Temperature compensation and simultaneous temperature measurement;
  • New magnetic materials for use in optical fiber magnetic field and current sensing;
  • Reliability of installed commercialized of magnetic and electric optical sensors.

We report on a study of the temperature dependence of the response of a BSO crystal based polarimetric current sensor with spectral interrogation. Two possible interrogation schemes are discussed. The spectral dependence of the optical rotation along the crystal caused by temperature and current changes is investigated, and approximate dependences for the sensitivities to current SI and temperature ST are derived. A mixed term in the response with spectral interrogation is revealed, the elimination of which is achieved by tracking wavelength shifts Δλ1 and Δλ2 of two distinct extrema in the polarimetric response. A temperature independent second degree equation for the current changes ΔI as a function of the measured spectral shifts is derived and tested. Full article
