  • Method of manufacturing an integrated optical waveguide
    Publication number: 20060096324
    Abstract: A waveguide includes a substrate, lower cladding having a decreasing cross-section, and a core having an increasing cross-section. The lower cladding is formed on a substrate, and the waveguide core is formed on the lower cladding. The waveguide core includes a first tract of constant thickness and a second tract of varying thickness, and finally side and upper cladding of the waveguide is formed. In order to obtain a waveguide having a segment of varying thickness in an easy, controlled and adiabatic manner, two series of operations are carried out to form the lower cladding and the core.
