For optical channels transmitting signals of weak power, several information criteria, such as the channel capacity, the cutoff rate and the rate distortion, are analyzed. These performances are calculated for various formats of modulation and for systems that include optical amplifiers and utilize photon-counting receivers. Comparison with the results that are derived from the Gaussian approximation of the intensity distribution is made.
