520    This thesis combines highly accurate optical spectroscopy 
       data on the recently discovered iron-based high-
       temperature superconductors with an incisive theoretical 
       analysis. Three outstanding results are reported: (1) The 
       superconductivity-induced modification of the far-infrared
       conductivity of an iron arsenide with minimal chemical 
       disorder is quantitatively described by means of a strong-
       coupling theory for spin fluctuation mediated Cooper 
       pairing. The formalism developed in this thesis also 
       describes prior spectroscopic data on more disordered 
       compounds. (2) The same materials exhibit a sharp 
       superconductivity-induced anomaly for photon energies 
       around 2.5 eV, two orders of magnitude larger than the 
       superconducting energy gap. The author provides a 
       qualitative interpretation of this unprecedented 
       observation, which is based on the multiband nature of the
       superconducting state. (3) The thesis also develops a 
       comprehensive description of a superconducting, yet 
       optically transparent iron chalcogenide compound. The 
       author shows that this highly unusual behavior can be 
       explained as a result of the nanoscopic coexistence of 
       insulating and superconducting phases, and he uses a 
       combination of two complementary experimental methods - 
       scanning near-field optical microscopy and low-energy muon
       spin rotation - to directly image the phase coexistence 
       and quantitatively determine the phase composition. These 
       data have important implications for the interpretation of
       data from other experimental probes.
