Tunable graphene antennas for selective enhancement of THz-emission

Filter, R.; Farhat, M.; Steglich, M.; Alaee, R.; Rockstuhl, C.; Lederer, F.

Abstract:
In this paper, we will introduce THz graphene antennas that strongly enhance the emission rate of quantum systems at specific frequencies. The tunability of these antennas can be used to selectively enhance individual spectral features. We will show as an example that any weak transition in the spectrum of coronene can become the dominant contribution. This selective and tunable enhancement establishes a new class of graphene-based THz devices, which will find applications in sensors, novel light sources, spectroscopy, and quantum communication devices.
