THz Amplifiers with Gain Medium and Field-enhancement Effect

Abstract (in Japanese) (See Japanese page) 
(in English) THz devices have been developed over the last decade to utilise THz waves for non-destructive sensing and high-speed wireless communications. Ryzhii et al. theoretically demonstrated the feasibility of THz lasing in optically pumped multiple graphene layer (MGL) and proposed THz laser structures. In addition, metallic sheets perforated with periodic holes (metal mesh) have been used for band-pass filters with resonant transmittance of unity. In these periodic structures, induced surface plasmon polaritons (SPP) enhance the electric field near the holes. We investigate THz amplifiers composed of MGL and metal mesh structures using FDTD electromagnetic simulation.
