Abstract

A system comprising an aluminum nano-antenna array on top of a luminescent colloidal quantum dot waveguide and covered by a thermotropic liquid crystal (LC) is introduced. By heating the LC above its critical temperature, we demonstrate that the concomitant refractive index change modifies the hybrid plasmonic-photonic resonances in the system. This enables active control of the spectrum and directionality of the narrow-band (~6 nm) enhancement of quantum dot photoluminescence by the metallic nano-antennas.
