Abstract
A fiber optic curvature sensor based on a tapered single-mode optical fiber coated with a polyester polymer (T-SMF-CPP) is proposed and experimentally demonstrated. Fabrication of the tapered optical fibers was realized by heating and stretching by a flame, and an airbrush was used to coat the surface of the tapered fiber with the polymer. The operating principle of the sensor was based on the interaction of the evanescent wave with the polyester polymer deposited on the tapered fiber. By adopting intensity demodulation in experiments, average sensitivities of -5.017 dB/m-1 and 5.862 dB/m-1 in the curvature ranges from 1.23 to 4.44 m-1 and from 4.64 to 7.54 m-1, respectively, were obtained for a fixed wavelength of
$\lambda =1572.45$
nm. The curvature of the sensor did not show a temperature dependence in the range [24-90 °C].
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.
