Abstract
Modal properties of disordered optical structures, including a 1D-like multilayer structure and a 2D planar slab, have been numerically simulated in the Mid-IR region. The amount of scattering and the disorder level have been varied. A Finite Element Method solver has been used to show the modal properties of these structures, highlighting the correlation between the spectral behavior and the amount of disorder. The quality factor has also been investigated. A statistical parameter, based on the definition of photons travel distance, has been proposed to give a measure of the disorder according to the modal properties. With the help of a Monte Carlo based software this parameter has been investigated to verify its suitability.
