Here we propose a new method to achieve direction-tunable emission based on a compact metallic microcavity with double nanoslit. Our method combines the principles of Young’s interference and surface plasmon polaritons interference. We show that the direction of the far-field beam can be controlled over a wide range of angles by manipulating the frequency and relative phase of light arriving at the two slits, which holds promise for applications in the ultracompact optoelectronic devices. https://ris.uni-paderborn.de/download/3832/3833/2017-06 Xiahong_Direction-tunable enhanced emission from a subwavelength metallic double-nanoslit structure_Optics Express.pdf application/pdfno The Optical Society2017 eng tet_topic_plasmonics 1094-40873832510.1364/oe.25.013207 251213207-13214 Song, Xiaohong, et al. “Direction-Tunable Enhanced Emission from a Subwavelength Metallic Double-Nanoslit Structure.” <i>Optics Express</i>, vol. 25, no. 12, The Optical Society, 2017, pp. 13207–14, doi:<a href="https://doi.org/10.1364/oe.25.013207">10.1364/oe.25.013207</a>. @article{Song_Wang_Yan_Lin_Förstner_Yang_2017, title={Direction-tunable enhanced emission from a subwavelength metallic double-nanoslit structure}, volume={25}, DOI={<a href="https://doi.org/10.1364/oe.25.013207">10.1364/oe.25.013207</a>}, number={12}, journal={Optics Express}, publisher={The Optical Society}, author={Song, Xiaohong and Wang, Nini and Yan, Ming and Lin, Cheng and Förstner, Jens and Yang, Weifeng}, year={2017}, pages={13207–13214} } Song X, Wang N, Yan M, Lin C, Förstner J, Yang W.
