Optical fiber sensor for the measurement of electric field intensity and voltage (OPSEF)

On-line testing of high power electromagnetic devices is one of the most important problems of modern industrial metrology. In the paper, the results of experimental investigations of the electric field optical fiber sensor based on the electroluminescent phenomena are presented. The electro¬luminescent effect is observed in some composite semicon¬ductors, among others in zinc sulfide ZnS crystals. In our investigations, the used ZnS crystal was doped with copper Cu atoms as activators. The concentration of activator in the ZnS crystal was about 5.10-4 [g/g]. According to plans of investi¬gations of the elaborated electroluminescent sensor, the spectral properties as well as the intensity of light emission in sinusoidal alternating electric field were tested.Full Text: PDF References:K.T.V.

Function expansion of fiber sensor is highly desired for ultrasensitive optical detection and analysis. Here, we present an approach of multifunctional fiber sensor based on Fano resonances and localized surface plasmon resonance (LSPR) excited via cylindrical vector beam with ability of refractive index (RI) sensing, nano-distance detection, and surface enhanced Raman spectroscopy (SERS). Silver (Ag)-nanocube modified microfiber is theoretically proved to enable to detect RI of the nearby solids and gases based on Fano resonances with a sensitivity of 128.63 nm/refractive index unit (RIU) and 148.21 nm/RIU for solids and gases, respectively. The scattering spectrum of the Ag nanocube has the red-shift response to the varies of the nano-distance between the nanocube and the nearby solid, providing a detection sensitivity up to 1.48 nm (wavelength)/nm (distance). Moreover, this configuration is theoretically verified to have ability to significantly enhance electric field intensity. Radially polarized beam is proved to enhance the electric field intensity as large as 5 times in the side-face configuration compared with linear polarization beam. This fiber-based sensing method is helpful in fields of remote detection, multiple species detection, and cylindrical vector beam-based detection.

Whispering Gallery

Abstract For the measurement of micron-sized components, there are many methods widely used, such as by using CMM, and the size of the probe sphere of CMM is essential for measuring. In order to accurately measure the size of the probe sphere, a method by using Whispering Gallery Mode (WGM) resonance has been proposed. To measure the diameter of the microsphere with this method, the resonance wavelength and the angular mode number of WGM need to be known. The resonance wavelength can be measured by a wavelength meter and the angular mode number can be obtained by using the near-field optical fiber probe to measure the electric field intensity distribution on the surface of the microsphere. The detecting sensitivity of probe on electric field intensity is quite important for angular mode number measuring, which is deeply related to the accuracy of microsphere diameter measurement. In the process of electric field intensity detecting, the sensitivity of the probe can be affected by its shape. Therefore, the effect of probe tip shape on measurement was studied to optimize it. In this study, the effect of probe tip diameter, angle and shape on the measuring of electric field intensity on microsphere surface was investigated.
