OPTICAL SWITCHING DEVICE COMPRISING TWO WAVEGUIDES WHEREOF BOTH SMALLEST DIMENSIONS ARE LESS THAN THE GUIDED WAVELENGTHS

摘要

Each guide 1, 2 has an elongate shape, comprises an input to one end and an output to the other end is arranged on the surface so that all the inlet ends of all the guides can be simultaneously illuminated in a zone 3 by the said radiation to be switched; according to the invention, each waveguide is made in a different material, preferably, the waveguides 1, 2 have approximately the same dimensions, which makes it possible to obtain the switching means is particularly economical.
