ABSTRACT:
The invention is directed to a method for making integrated optical components having strip waveguides (11 to 15; 21 to 2M) and a layer waveguide 53. A mask 4 having a lattice structure 3i functions to generate the layer waveguide 53 via ion exchange. The method of the invention is suitable for making couplers having free spaces with low attenuation and is especially suitable for arrayed waveguide grating multiplexers. The invention also is directed to an integrated optical component made pursuant to the method of the invention.
