Paper Abstract

In this paper, we studied the silicon nitride waveguide phase modulator using graphene as a heating electrode. We demonstrate the advantages of graphene heater waveguide phase shifter by comparative simulation, The effect of the length and the width of the heating electrode on the thermal phase modulating efficiency was also been studied. Finally, by covering the graphene heating electrode directly on the waveguide, we obtained a low-power thermal-adjustable phase shifter with a π-phase shift modulation power of 96.8mW.
