Abstract
Van der Waals materials, with their unique properties, have significantly advanced research in integrated photonics. Among these materials, hexagonal boron nitride (hBN) stands out for its optically and electronically desirable characteristics, including on-chip integration, availability, and manipulability. Particularly noteworthy are hBN's colour centres, which serve as single photon emitters in the UV and visible spectrums, essential for quantum communication and computing applications. Enhancing and controlling the emission wavelengths and quality is crucial. Plasmonic cavities, a common method for emission enhancement, are utilized in our study, employing plasmonic nanocones to investigate both the enhancement and the variability in emission wavelength. Our observations reveal a power dependence in emitter quenching. We substantiate our findings by comparing results from unstrained hBN without plasmonic enhancement with simulations. Additionally, we discuss the impact of gold emission on the quality of these emitters, providing valuable insights into the mechanisms at play.
