Abstract
Tunable UV devices can enable enhanced functionalities such as multiplexed sensing, wavelength-tunable light emission and so on. Interestingly, in the UV range, graphene shows a tunable optical absorption due to pi-plasmon resonance. In this work we study the UV transmission through monolayer graphene films transferred on top of aluminum hole-arrays. Transmittance though the hole-array was measured before and after graphene transfer. Interaction of graphene pi-plasmons with surface plasmon resonances leads to strong wavelength shifts, i.e. the surface plasmon resonance at the top-interface red-shifts when graphene is added. Furthermore, it is observed that maximum shift occurs in the 280 to 310 nm wavelength range. This is attributed to an enhanced graphene optical conductivity owed to pi-plasmons.
