In the paper "Cavity enhanced third harmonic generation in graphene," we reported third harmonic generation from a graphene-dielectric-metal cavity. Since the original publication, it has come to light that a rather severe error was made in the calibration of the detector used in the experiments. Correcting this error (see corrected Figs. 1 and 2) leads to significantly lower absolute powers than previously reported, and power conversion efficiencies approaching ∼10-8 (for the largest powers used in the experiment) when resonant with the cavity and ∼10-10 when off resonance. The off resonance conversion efficiency is in line with previously reported values for planar graphene measured with comparable pulse fluence.1 Note that, due to a miscommunication between the authors, this error did not propagate into the numerical modeling results from the paper, i.e., our pW output powers are in line with v3 of order 10-17 m2=V2, as found in the analytical modeling of Ref. 2. It should also be noted that the main conclusion of our original paper, i.e., a two orders of magnitude enhancement in the harmonic generation due to the cavity, is unaffected by this error.

Abstract

In the paper "Cavity enhanced third harmonic generation in graphene," we reported third harmonic generation from a graphene-dielectric-metal cavity. Since the original publication, it has come to light that a rather severe error was made in the calibration of the detector used in the experiments. Correcting this error (see corrected Figs. 1 and 2) leads to significantly lower absolute powers than previously reported, and power conversion efficiencies approaching ∼10-8 (for the largest powers used in the experiment) when resonant with the cavity and ∼10-10 when off resonance. The off resonance conversion efficiency is in line with previously reported values for planar graphene measured with comparable pulse fluence.1 Note that, due to a miscommunication between the authors, this error did not propagate into the numerical modeling results from the paper, i.e., our pW output powers are in line with v3 of order 10-17 m2=V2, as found in the analytical modeling of Ref. 2. It should also be noted that the main conclusion of our original paper, i.e., a two orders of magnitude enhancement in the harmonic generation due to the cavity, is unaffected by this error.
