摘要
Hybrid photonic-plasmonic cavities based on nanoparticle-on-a-mirror structures simultaneously provide ultralow mode volume and high $Q$-factor, and so a very large Purcell factor, which is a key measure of light-matter interaction. Operation of such cavities has been constrained to wavelengths below 1 \ensuremath{\mu}m, with the technologically relevant telecom regime remaining elusive. This study describes a hybrid cavity operating at telecom wavelengths. The proposed design leads to extremely large Purcell factors (~10${}^{7}$--10${}^{8}$), and could impact many different applications, such as molecular optomechanics, bio- and chemosensing, efficient quantum emitters, and enhanced Raman spectroscopy.
