Abstract

Tunable directional emission from electrically driven sources is essential for applications involving on-chip nano-circuits, sensing and quantum information processing. Here, we numerically demonstrate wavelength selective, switchable directional emission from periodic, nano-strip metal-insulator-metal tunnel junctions. Using two excitation sources, we show that our structure can efficiently redirect two different wavelengths in opposite directions when the excitation is switched. We achieved a peak directivity of 21.5 and 25.8 for wavelengths of 692 nm and 738 nm, respectively. The emission angle can be tuned by varying the periodicity, thereby paving the way for on-chip multiplexing. © 2022 IEEE.
