Abstract :
In the present work, we design and fabricate omnidirectional mirrors based on 1D photonic crystals made of chalcogenide and cryolite using thermal evaporation. In particular, a two-dimensional mapping that provides a direct, visual signature of the mirrors is proposed. An experimental measurement of the reflectivity is shown. Finally a mirror with an omnidirectional reflectivity of more than 94% for a general polarization, a TE omnidirectional reflectivity of more than 99%, and a TE reflectivity of more than 99.99% for high incident angles is presented. The surface roughness of the mirrors is less than 5nm.
