Abstract

We have demonstrated gate-tunable sub-nanosecond conversion of THz light to visible UV light in graphene [1]. Electrostatic gating in the range of 1-2 V allows to change the conversion efficiency by a factor of 30. An additional metallic grating, which enhances the THz electric field, increases the optical emission by 2 orders of magnitude. The observed optical radiation comes from blackbody emission of the graphene electron system heated by intraband Drude absorption of THz light.
