Abstract

We demonstrate Brillouin-mediated microcomb multiplexing in a surface nanoscale axial photonic resonator. Continuous-wave pumping drives cascaded stimulated Brillouin scattering, generating frequency-shifted fields that seed Kerr four-wave mixing. The nonlinear spectrum contains two comb families with the same azimuthal spacing, approximately 100.2 GHz, but offset from one another by approximately 9.6 GHz, consistent with the Brillouin shift in silica. These results show that cascaded Brillouin lasing can generate multiple related comb channels in a single axially structured whispering-gallery-mode resonator.
