Magnetodispersion of two-dimensional plasmon polaritons

We have investigated the spectrum of two-dimensional (2D) plasmon polaritons over the full range of magnetic fields. In our study, we investigate a disk-shaped two-dimensional electron system (2DES) with a metallic gate on the backside of the substrate. Importantly, we show that 2D plasmon polaritons hybridize with the TM0 photonic mode of a dielectric waveguide formed by a sample substrate. We have developed a theory for plasmon-polaritons in an infinite 2DES. We find the experimental data to be in good agreement with the developed theory.

Automated summary

The spectrum of two-dimensional plasmon polaritons over the full range of magnetic fields was investigated, with a focus on their hybridization with the TM0 photonic mode of a dielectric waveguide. A theory for plasmon-polaritons in an infinite 2DES was developed and found to be in good agreement with experimental data.
