Abstract

We introduce a new scheme of actively controlling the $P T$ symmetry of the graphene Dirac plasmon metasurface in a graphene-channel laser transistor structure. Numerical simulation demonstrates the capability of 100-Gbit/s-class ultrafast gain-switching in its plasmonic THz laser operation by electrically modulating the $P T$ symmetry by the applied bias voltages.
