Abstract
The present invention relates to a semiconductor emission device with fast wavelength modulation and constituted by three sections, namely two lateral sections, each having an active layer and a DFB network and which produce an optical gain, connected across a central electroabsorbant section, to which is applied a reverse voltage making it possible to quasi-instantaneously modify the absorption rate in said section.
