| contents | We report the observation of optically-induced mechanical oscillations in flame-produced surface nanoscale axial photonic resonators (SNAPRs). The frequency of the optically-excited mechanical modes in these SNAPRs is not affected by the particulars of the optical axial confinement, and matches with the theoretically predicted frequency for the fundamental breathing mode of an infinite solid cylinder. When the SNAPR fabrication recipe is changed, changing the optical mode spectrum, the behaviour of the observed mechanical modes remains unchanged. This shows a degree of geometrical uncoupling between the optical and mechanical degrees of freedom, which in turn implies the effective radius variation causing axial optical confinement in our SNAPRs is dominated by a refractive index change rather than a physical radius change. |
