Abstract

The per-sample zero-dispersion channel model of the optical fiber is\nconsidered. It is shown that capacity is uniquely achieved by an input\nprobability distribution that has continuous uniform phase and discrete\namplitude that takes on finitely many values. This result holds when the\nchannel is subject to general input cost constraints, that include a peak\namplitude constraint and a joint average and peak amplitude constraint.\n
