Abstract
We propose and experimentally demonstrate capacitive actuation of a grapheneâsilicon micro-ring add/drop filter. The mechanism is based on a siliconâSiO2âgraphene capacitor on top of the ring waveguide. We show the capacitive actuation of the add/drop functionality by a voltage-driven change of the graphene optical absorption. The proposed capacitive solution overcomes the need for continuous heating to keep tuned the filterâs in/out resonance and therefore eliminates âin operationâ energy consumption.File in questo prodotto:
