The Joule loss profiles of different structure at two wavelengths in a double layered magneto-optical disk

The optical matrix method was used to calculate the light intensity distributions and the Joule loss profiles in a typical double-layered MO disk. We attained the Joule loss profiles of the different thicknesses of dielectric layers SiN and the substrate with various refractive index at two wavelengths. If the suitable thicknesses of dielectric layers and the substrate were chosen, the desired Joule loss profiles inside the MO disk can be designed. This implies that the optical matrix method is an effective tool to select material in designing MO disk.
