Paper Abstract

We investigate the superfluid and quasiparticle response for high temperature superconductor films of YBa2Cu3O7 and Ba0.6K0.4BiO3 under optical radiation. This is done through direct measurement of the complex conductivity of the illuminated superconductors using a coherent terahertz-bandwidth spectroscopy technique. The nature of the detected signals is discussed in the context of bolometric and nonbolometric response.
