Abstract:
A method of manufacturing an integrated optical component comprising a thick waveguide coupled to a thin waveguide via a coupling interface, said method consisting in:depositing a first guiding layer of said thick waveguide on a substrate;locally etching said first guiding layer over a portion allocated both to the coupling interface and to the thin waveguide;depositing a second guiding layer on the first guiding layer and on the locally etched portion so as to form said thick waveguide in a manner such that it has a maximum thickness in a first zone, a graded-thickness section in a second zone, and a reduced-thickness section in a third zone;locally etching the second guiding layer over a portion of the third zone, said portion being allocated to the thin waveguide; anddepositing a third guiding layer in said portion of said third zone so as to form said thin waveguide.
