| 摘要 |
The invention relates to a semiconductor electro-optical monolithic component. The component is made up of at least two sections, each of which has a respective waveguide, the waveguides being etched in the form of ridges, disposed in line, and buried in a cladding layer. The sections are electrically isolated from one other by a resistive zone. At the interface between two sections, the waveguides are locally of an extended width not less than the width of the resistive zone.
