Abstract: Azobenzene containing polymers exhibit strong surface relief features when irradiated with polarized light. Here we propose a theory based on elastic deformation of the polymer due to interaction between dipoles ordered through polarized light irradiation. The effects are due to the presence of boundary layer. The observation of both wells and humps dependent on the architecture of the polymer can be explained with the present theory.
