Abstract
We propose and demonstrate a temperature compensation method based on the inherent polarization quality factor (PQF) of the quarter-waveplate in the fiber optic current sensors. The PQF, dependent on the temperature, can act as a temperature sensor with a resolution of $2~^{\circ }$ C in the experiment. The new compensation coefficient based on PQF is derived from the both relationships of the PQF and the temperature-dependent ratio error. This method can achieve the temperature compensation through internal PQF value instead of direct temperature, and need not require an external temperature sensor to monitor ambient temperature. The new compensation can achieve the accuracy of ratio error 0.2% within the temperature range of $- 40~^{\circ }$ C to $+ 72~^{\circ }$ C, which is satisfied with the 0.2 Class accuracy.
期刊介绍：
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
