A theory of optical conductivity due to the competition between interlayer direct hopping and hopping assisted by spin fluctuations has been developed. The prediction of our theory captures the main feature of the experiment. Thus, we argue that the anomalous behavior of the c ‐axis optical conductivity in the underdoped cuprates may be properly understood within the theory.
