[CMP3B-01 (Invited)] Controlling the Non-Hermitian Graphene Dirac Plasmons and Its Application to Terahertz Laser Transistors

*Taiichi Otsuji1 (1. Tohoku University (Japan))

[Presentation Style] Onsite

We introduce a new scheme of actively controlling the non-Hermitian Dirac plasmons in a graphene-channel laser transistor structure. Numerical simulation demonstrates the capability of 100-Gbit/s-class ultrafast gain-switching by electrically modulating the PT symmetry.
