Study on Information Entropy Representing Nonlinear Propagation of Light
The information entropy in quantum mechanics is introduced to represent nonlinear propagation of light within the framework of the Schroedinger formulation of light propagation. Our analytical derivation and numerical calculation show that the information entropy and its differentiation with respect to the propagation direction can describe the compression and broadening of light pulse (or the focusing and diffussion of light beam), which is better than the description with pulse (beam) width and second order moments.
