Paper Abstract

We report on sub-wavelength THz plasmonic split ring resonators on 2 dimensional electron gas (2DEG) at AlGaN/GaN hetero-interface and on oxide coated high mobility graphene. The investigated in this study guide THz electric field into deep sub-wavelength scale by plasmonic excitations. Propagation of a broadband pulse of EM waves was simulated by using a commercial FDTD simulation tool. The results show that split ring resonator structures can be used to guide THz into deep sub-wavelength down λ/200 and achieve relatively higher quality factors than grating gate devices by plasmonic confinement which can be used for THz detection, filtering and possibly for THz on-chip-spectrometer. Moreover, ring resonator modes supported by system can be tuned with an applied voltage to gratings.
