Abstract

Light trapping in homogeneous media with saturable nonlinearity is examined. Trapping of light is found to be possible in any saturable nonlinear material so long as its maximum allowed refractive-index change is positive. However, quite different from Kerr nonlinearity, trapping powers of trapped light in a saturable nonlinear medium can depend sensitively on the effective propagation constant of the trapped modes and the maximum allowed intensity-induced refractive-index change.
