Abstract

We report strong THz-induced transparency in CVD-grown graphene where 92-96% of the peak-field is transmitted compared to 74% at lower field strength. Time-resolved THz pump/THz probe studies reveal that the absorption recovers in 2-3 ps. The induced transparency is believed to arise from nonlinear pumping of carriers in graphene which suppresses the mobility and consequently the conductivity in a spectral region where the light-matter interaction is particularly strong.
