Linearons: Solitons propagating in liquid-core photonic crystal fibers

In a recent work, we have reported that if the central core is filled with liquids with a slow reorientational nonlinearity (such as CS 2 or toluene), the equation describing nonlinear light propagation becomes a linear Schrodinger equation, with a discontinuous potential proportional to the total energy of the pulse and to the response function R(t) itself. This is temporal analogue of the concept of 'accessible solitons' elaborated in 1997 by Snyder and Mitchell in the case of spatial solitons.
