Abstract
This paper presents a comprehensive study of light reflection modulation in graphene through external applied voltage and shows a strategy to realize both broadband and strong reflection enhancement. The influence of chemical potential, applied voltage and carrier concentration on reflection efficiency are investigated by numerical simulations. By employing an applied voltage, the maximum of difference of reflected coefficient can reach up to 30% for 3THz radian frequency. Thus, using external voltage to control optical reflection efficiency is testified to be reasonable and feasible based on graphene film. Furthermore, the reflection efficiency modulation can be realized at a wideband of frequency.
