Summary:  We give a necessary condition for a Cowen--Douglas operator to be similar to the backward shift operator on the Dirichlet space. A model theorem for weighted shifts provides an eigenvector bundle structure for the operators involved and plays a fundamental role in this geometric description.

Keywords:  backward shift, Cowen-Douglas operator, Dirichlet space, eigenvector bundle, reproducing kernel, similarity
