Abstract

Graphene is an ideal material for optoelectronic applications. The photonic properties of graphene reveal several advantages and complementarities compared with Si photonics. For example, graphene exhibits electro-absorption modulation, electro-refraction modulation with an electro-optical index change exceeding 10−3, switchable optical add-drop multiplexing based on electro-absorption switch-off and thermoelectric-based ultrafast optical detection that may generate a voltage without a trans-impedance amplifier. In this Review, we present our vision for graphene-based integrated photonics. We review state-of-the-art graphene-based transceivers and compare these devices with existing technologies. Strategies for improving power consumption, manufacturability and wafer-scale integration are addressed. Also, we outline a roadmap of the technological requirements for the demands of the datacom and telecom markets and show that graphene-based integrated photonics could enable ultra-high spatial density, low power consumption for board connectivity and connectivity between data centres, access networks, metropolitan, core, regional and long-haul optical communications.
