Optical fiber sensors, are one family of devices that are used for this purpose. In this paper, Graphene was used to increase the sensitivity of long period grating sensors. In the first step the sensor was fabricated, then refractive index measurement with bare and graphene coated sensors was done. By study these results of tests the effect of graphene on the sensitivity was investigated. More than 5 times increase in the sensitivity was observed. }, URL = {http://opsi.ir/article-1-744-en.html}, eprint = {http://opsi.ir/article-1-744-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2015} }
