The authors investigate the superfluid and quasiparticle response for high temperature superconductor films of YBa{sub 2}Cu{sub 3}O{sub 7} and Ba{sub 0.6}K{sub 0.4}BiO{sub 3} 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.
