Abstract
We report in this paper a numerical study of optical switching in coup lers with saturable nonlinearity. Regions that characterize different coupling behaviour are revealed. It is shown that, in the presence of saturation, a Gaussian pulse should be used instead of solitons for ne gligible pulse splitting between the coupler arms. Nearly complete swi tching is possible depending on the input optical power and the index saturation parameter.
