Abstract
The four layer planar metal-clad optical waveguide is shown to provide favourable transmission for TM waves in comparison with TE waves when a thin high-index buffer layer is inserted between the guiding film and the metallic layer. A perturbative expression for the loss of the two polarisations is given.
