Abstract
In a method of manufacturing a planar optical waveguide based entirely on polymer materials an active polymer is deposited onto a semiconductor substrate between two layers of buffer polymers chosen so that the difference in refractive index on each side of the active polymer is between 0.005 and 0.5 and preferably between 0.01 and 0.4.
