Abstract
A method for adjusting the properties of a photonic circuit such that they fit with expected properties, the photonic circuit including a waveguide which includes a light propagation region, is provided. The method includes a step of modifying the refractive index of at least one zone of the region, the step being implemented by an ion implantation in the at least one zone. It extends to a waveguide the light propagation region of which has at least one zone with a refractive index modified by ion implantation in which the light remains confined, as well as a photonic circuit incorporating such a guide.
