Abstract

Each guide has an elongated shape, comprises an input at one end and an output at the other end, is arranged on the surface such that all the input ends of all the guides can be simultaneously illuminated in one zone by said radiation to be switched. The invention is characterized in that each guide is produced in a different material; preferably, the guides have more or less the same dimensions, thereby enabling to obtain particularly economical switching means.
