GRAPHENE BASED OPTICAL FIBRE SENSORS: A REVIEW

Abstract

In various scientific fields, like chemistry, physics and materials science, Graphene (G), a two-dimensional carbon material of one-atom-thickness, is becoming a growing subject. After Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved isolation in 2004, graphene and its compounds have been the most studied materials. The extraordinary properties of graphene have drawn the science community's attention from numerous fields of study, creating a high influence not just in scientific journals as well as in newspapers of personal interest. By utilizing graphene materials, a broad range of chemical sensors, biosensors, and gas sensors have been produced. One of the many areas that will benefit through the use of such modern methods is optical fibre sensing, integrating the incredible morphological, chemical, optical and electrical properties of graphene with the benefits given by optical fibre over other sensing techniques. A analysis of the latest state of the art for optical fibre sensors based on graphene materials is reviewed in this article.
