Polarization anisotropy of single crystal opal films

Single-crystal opal films have been prepared by the moving-meniscus and gravitational sedimentation methods. It has been found using conoscopy and spectroscopic ellipsometry that these photonic crystal opal films possess birefringence so that the optical indicatrix is a three-axial ellipsoid. The in...

Description
Summary:Single-crystal opal films have been prepared by the moving-meniscus and gravitational sedimentation methods. It has been found using conoscopy and spectroscopic ellipsometry that these photonic crystal opal films possess birefringence so that the optical indicatrix is a three-axial ellipsoid. The indicatrix axis N g is directed along the crystal growth axis, the axis N m lies in the film plane and is orthogonal to the axis N g , and the axis N p coincides with the normal to the (111) crystallographic plane, which corresponds to the triclinic system of the crystal.
