Abstract

Integrated optical waveguides, for example planar waveguides with stripes of guiding material formed integrally on a substrate, are manufactured by depositing the doped glass guiding material by plasma chemical vapor deposition. Several substrates can be arranged in a suitably shaped apparatus so that deposition can take place on all of them at once.
