Abstract
We employ the Bardeen-Cooper-Schrieffer theory to calculate the frequency-dependent interlayer conductivity of a superconducting bilayer, the two layers of which are coupled by weak single-particle tunneling. The effect of the superconducting transition on the normal-state absorption band is to blue-shift and broaden it, while causing the peak absorption to be reduced and the line shape to become asymmetric.
