Optical arrangement and device configuration. a Optical path diagram of the incident light from air to graphene/substrate medium. b The reflection amplitude and (c) phase as a function of incident angle, when the graphene conductivity is at 0 and 3.7 mS. The yellow arrows indicate the modulation of intensity and phase. d The three-dimensional (3D) diagram of the device, and (e) the SEM image of the cross section of the device. The scale bar is 5 µm
