Graphene, as well as nanocomposite materials (NCMs), reveal some striking optical properties, and photonic devices based on the composition of these two elements may display superior performance. In this article, we investigate Goos-Hanchen (GH) shifts for the reflected and the transmitted part of a light field incident on a geometry containing graphene sandwiched between an Ag-SiO2 composite film and a dielectric. Apart from the fact that the Ag-nanoparticles in the NCM and the graphene are both highly absorbing in the visible spectrum, we observe huge lateral shifts in this case. We further demonstrate that the sign as well as magnitude of these shifts can be efficiently adjusted by tuning, either individually or simultaneously, a number of controlling parameters corresponding to different media in the present model. This high order tunability of the GH shifts using this model can be useful to design highly accurate sensors and optical switches. Published under license by AIP Publishing.
