We introduced a new scheme of actively controlling the PT symmetry of the GDP metasurface in a DGG-GFET. The PT symmetry can be modified by the applied bias voltages. Numerical simulation demonstrated the capability of 100-Gbit/s-class ultrafast gain-switching in its plasmonic THz laser operation. The work was supported by JSPS KA-KENHI # 21H04546, #20K20349, and #21H04546, Japan.

N2 - We introduce a new scheme of actively controlling the PT 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 PT symmetry by the applied bias voltages.
