GRADIENT-INDEX MICROLENSES - NUMERICAL INVESTIGATION OF DIFFERENT SPHERICAL INDEX PROFILES WITH THE WAVE PROPAGATION METHOD

摘要

Ion-exchange microlenses are available with different gradient-index profiles. We investigate the dependence of the imaging properties on the steepness of the index profiles. Therefore we model the index distribution by the Fermi function as radial distribution with spherical symmetry. The results are compared to index profiles according to the Doremus model.
