Process for the production of a birefringent strip waveguide in an integrated optical component, and an integrated optical component produced by the process

摘要

An integrated optical component contains a waveguide (4) having a birefringent waveguide section (7) between two non-birefringent waveguide sections (17, 18) along the surface of a glass substrate (1). The production of the birefringent waveguide section (7) and the non-birefringent waveguide sections (17, 18) is carried out in a first and second ion exchange process through a first and a second diffusion mask with the aid of a first salt melt for the first ion exchange process and a second salt melt of different composition for the second ion exchange process.
