Abstract
Photomigration in azo polymers is an area of research that witnessed intensive studies owing to its potential in optical manipulation; e.g. optical tweezing; the physical mechanism of which remains unsolved since its discovery about two decades ago. In this presentation, a detailed theoretical study that reproduces the phenomena associated with photomigration is presented, including the physical models and the associated master equations. I discuss polarization effects and I give the analytical solutions describing the steady-state and the dynamics of photomigration.
