摘要
We have reported earlier the observation of a self-written waveguide inside a bulk methylene blue sensitized poly (Vinyl Alcohol) /Acrylamide photopolymer material [1]. In this work we develop a theoretical model to explain the experimental observation. We reduce the governing equations for the propagation of a low power laser beam through such a medium into the form of nonlinear Schrodinger equation with a cubic-quintic nonlinearity and solve this equation using variational method. It is found that there is agreement between experimental and theoretical results.
