%0 Journal Article %T Tensile Test Using Photonic Crystal %J - %D 2018 %X Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers present special properties and capabilities that lead to an outstanding potential for sensing applications. The objective of this project is to analyze the performance of photonic crystal fiber based strain sensors. PCF, injected PCF with olive oil , and MMF are used to compare between their sensitivity to the stress . It was concluded that the PCF is more sensitive to the stress than the MMF, and the injected PCF with olive oil is more sensitive to the stress than the PCF %K photonic crystal %K PCF %K fiber optics .strain sensor %U https://iiste.org/Journals/index.php/ISDE/article/view/43705
