Characterization of light-control-light system using graphene oxide coated optical waveguide

An optical waveguide was coated with graphene oxide (GO) using the drop-casting technique to increase the interaction between the waveguide's evanescent field and the GO layer. Subsequently, a 1550 nm tunable laser source and 980 nm pump laser is used to study the potential of the GO-film to co...
