Abstract

We demonstrate that the nonlinear optical response of graphene is resonantly enhanced by incorporating monolayer graphene into a Fabry-Pérot microcavity. The modulation depth of the microcavity-integrated monolayer graphene device is increased to 12% which is much higher than the value of about 2% in other works, while retaining an ultrafast recovery time of ~0.7 ps. This suggests possible application in ultrafast all-optical signal processing.
