Tunable Plasmonic Nanoantennas in Rolled-up Microtubes Coupled to Integrated Quantum Wells
Abstract
We propose and realize a tunable plasmonic nanoantenna design consisting of two stacked Ag cuboids that are integrated into a rolled-up semiconductor microtube. The antenna's resonance is tuned by varying the cuboid's distance to match the photoluminescence emission of an embedded GaAs quantum well. Spatially, spectrally and temporally resolved photoluminescence measurements reveal a redshift and a reduction in lifetime of the quantum-well emission as signatures for the coupling to the antenna system. By means of finite-element electromagnetic simulations, we assign the coupling to an excitation of a high-order plasmonic mode inside the Ag cuboids.
