Nonlinear studies of graphene oxide and its application to moisture detection in transformer oil using D-shaped optical fibre

This paper reports nonlinear optical response studies of thin layers using graphene oxide (GO) and their performance for detecting water content in transformer oil using three sets of approaches. The sensor performance is evaluated based on bare optical fibre, D-shape optical fibre integrated with G...
