Abstract:
Integrated optical channel waveguide system with a substrate (2) carrying a waveguide layer structure, comprising in succession a first cladding layer (4), a passive light guiding layer (8), an electro-optical light guiding layer (10) and a second cladding layer (12), characterized in that at least said passive light guiding layer and said electro-optical light guiding layer and said second cladding layer are provided along a longitudinal direction of the waveguide layer structure with an adiabatic transition zone (15, 24, 32, 36) formed by a continuous variation in the layer thickness in said direction, these layer thickness variations thereby enabling a mutually independent optimizing of each predetermined optical function within a combination of functions to be used in the waveguide layer structure.
