Plasmonic materials with relatively low thermal conductivity, such as titanium nitride, exhibit photothermal conversion behavior in which the surface temperature distribution of nanostructures is strongly influenced by the plasmonic modes. In this presentation, we report on the fabrication of titanium nitride nanostructures exhibiting chiral optical responses using nanofabrication techniques such as electron beam lithography. We experimentally investigated whether the surface temperature of these nanostructures could be switched by illuminating them with right- or left-handed circularly polarized light.
