The long‐term temperature induced errors caused by fiber λ/4 wave plate and the Verdet constant of sensing fiber in the all fiber current transformer (FOCT) are theoretically analyzed. A temperature related response of fiber λ/4 wave plate is adopted to compensate for the change caused by temperature related Verdet constant through choosing appropriate initial phase retardation of the λ/4 wave plate. The experimental results show high temperature‐cycle accuracy in this kind of FOCT with relative error within 0.6%.

“…However, the effect of this method is gradually decreased over time due to the release of the shearing stress produced by the torsion operation. The third method applies highly spun birefringence fiber as the sensing fiber [14]. However, the Verdet constant of this fiber is difficult to be evenly distributed.…”

In this work, an elimination method of the temperature-induced linear birefringence (TILB) in a stray current sensor is proposed using the cylindrical spiral fiber (CSF), which produces a large amount of circular birefringence to eliminate the TILB based on geometric rotation effect. First, the differential equations that indicate the polarization evolution of the CSF element are derived, and the output error model is built based on the Jones matrix calculus. Then, an accurate search method is proposed to obtain the key parameters of the CSF, including the length of the cylindrical silica rod and the number of the curve spirals. The optimized results are 302 mm and 11, respectively. Moreover, an effective factor is proposed to analyze the elimination of the TILB, which should be greater than 7.42 to achieve the output error requirement that is not greater than 0.5%. Finally, temperature experiments are conducted to verify the feasibility of the elimination method. The results indicate that the output error caused by the TILB can be controlled less than 0.43% based on this elimination method within the range from −20 °C to 40 °C.

“…So it is very important to develop a practical technique in order to eliminate the impacts of linear birefringence, or minimize the linear birefringence, and to enhance the sensitivity of sensing properties. Since the early 1990s, a spinning fibre method has been used in manufacturing the spinning fibre directly, instead of spinning preform, which has proven to be an effective technique to reduce the fibre PMD [10][11][12][13]. Recently, the spinning preform methods are used to draw single mode fibre, polarization maintaining fibre, Er-doped silica fibre, etc.…”

Spun related effects on optical properties of silica optical fibres have been investigated experimentally. In addition to the previously known spun effects on polarization mode dispersion (PMD), we observed previously unknown spun related effects on mode field diameter (MFD), cutoff wavelength and Verdet constant. These effects are significant at highly spun (short pitch length) fibres which are draw at high rotation rate and low drawing speed. By fabricating and testing spun fibres of varying pitch lengths, we found that MFD, cutoff wavelength and PMD all decrease as the pitch length decreases, while the fibre loss increases significantly when the pitch length is lower than 1.5 mm. We have also investigated the spun and annealing effects on Verdet constant of spun fibres. Our experimental results reveal that, by increasing the spun rate (i.e. decreasing the spun pitch length), the Verdet constant is increased appreciably. One relevant finding is that the increase of Verdet constant of spun fibres after annealing is inversely proportional to the pitch length. The overall Verdet constant increase, due to spun and annealing processes, can reach about 4.5% at 1550 nm wavelength in a spun fibre with 1.0 mm pitch.Index Terms-Fibre sensor, Magnate-optical property, Spun fibre, Verdet constant . 0733-8724 (c)
