▎ 摘  要

The polarization dependence of transient optical reflection, induced by nonequilibrium carriers isotropically distributed in momentum space, of graphene on substrate is experimentally and theoretically investigated. It is found that this transient optical reflection could be made greatly polarization dependent by using oblique incidence for light, and the characteristic of this polarization dependence could be flexibly altered with incident angle and incident direction (from graphene to substrate, or from substrate to graphene). Our results suggest that through polarization of incident beam is an efficient way of manipulating graphene transient optical reflection. (C) 2015 Optical Society of America
