Abstract
We experimentally investigate how the static and dynamic optical properties of cadmium oxide evolve with yttrium doping, for the design of optical and plasmonic devices spanning the near-infrared to the mid-infrared wavelengths. The metallicity is seen to increase and the epsilon-near-zero point blue-shifts with increasing yttrium-concentrations. We demonstrate broadband, optical-pump-induced reflection and transmission modulation ((up to 135% near ENZ), with picosecond response-times controlled by doping-concentration.
