We have investigated a ceramic sample of the high-temperature
superconductor Bi2Sr2CaCu2O8 (T(c) = 85 K) by infrared and visible
reflectance spectroscopy at several temperatures both below and above
the superconducting transition. We find that the temperature variation
in the vibrational region is associated with minima or antiresonance
features of the optical conductivity, instead of maxima, indicating
strong Fano-type electron-phonon interaction and implying that the
phonon structure in the infrared is strongly affected by the ab-plane
response.
