Abstract
Surface polaritons comprise a wealth of light-matter interactions with deep subwavelength scale confinement of electromagnetic modes. However, their nanoscale localized dissipation and thermalization processes are not readably accessible experimentally. Here, we introduce photo-thermal force microscopy to image the nonradiative surface plasmon polariton (SPPs) dissipation in monolayer graphene on SiO2. We demonstrate the real-space imaging of SPPs via photo-induced force detection, and by direct comparison with all-optical s-SNOM imaging we attribute this response to substrate dissipation-induced thermal expansion. This work illustrates that tip-sample nanocavity induced dissipative forces facilitate a direct mechanical detection of surface polariton interactions with monolayer sensitivity.Citation
