Abstract
The principle scheme of a new multilevel coherent optical system is presented which shows how to exploit the four degrees of freedom of the optical field. The proposed system performance gets nearer to the theoretical Shannon limit than conventional and polarisation modulated multilevel systems for a high number of levels.
