Erratum: “Cavity enhanced third harmonic generation in graphene” [Appl. Phys. Lett. 112, 011102 (2018)

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.
