dc.description.abstractLaunching and manipulation of light in Van der Waals materials has recently been seen as a promising strategy for many optoelectronic applications, such as molecular spectroscopy, photodetection and lasing among others. Particularly, the emergence of highly confined and diffraction unlimited hyperbolic polaritons has an enormous interest for guiding of light on deeply subwavelength scales (e.g. nano- and sub-nano scales in the terahertz and infrared frequency ranges). An efficient coupling to these polaritons is however hampered due to a large momentum mismatch between hyperbolic polaritons and free space photons. Here on the example of hyperbolic phonon-polaritons (HPhPs) in hBN slabs, we use resonant optical antenna to overcome the momentum mismatch. We reveal a strong coupling between Fabry-Perot plasmonic resonances in the gold antenna and phonons of h-BN in the upper Reststrahlen band. We find that some of the antenna modes can leak into propagating HPhPs, thus favoring the launching of the latter. Our findings demonstrate novel insights into use of van der Waals materials in photonics, particularly for control of light below the diffraction limit, on the nanoscale. Particularly, resonant antennas combined with these materials constitute a versatile technology that can be integrated into ultra-thin optoelectronic devices.es_ES
