Abstract

We have fabricated 2D photonic crystal films by holographic method. Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM) images show that the structures are two- dimensional in the sub-micrometric scale and the structure is perfectly ordered. The dimension in the plane of the films can be up to 50x50 mm². Both triangular and square Lattices were made. Band structure was also simulated using the plane wave expansion method. We tried in particular to better control the fabrication process in order to have the photonic gap in the desired wavelength range.
