Abstract

We demonstrate a graphene-based electro-absorption modulator with extremely small modulation volume that can be controlled by low gating voltages 1-3 V and shows light modulation at wavelengths as short as 900 nm. Our choice of hafnium oxide dielectric separator gives the possibility to obtain significant electro-optical effect in a simple optical heterostructure. Having low power consumption, our devices could find a wide range of applications in telecom industry.
