Abstract-Photoinduced Nonlinear Mixing of Terahertz Dipole Resonances in Graphene Metadevices
in a hybrid graphene metadevice is reported. Decades of research have revealed that terahertz-wave generation is impossible in single-layer graphene. This limitation is overcome and nonlinear terahertz generation by ultra-short optical pulse injection is demonstrated. This device is an essential step toward atomically-thin, nonlinear terahertz optoelectronic components.
