Zusammenfassung:	An optical waveguide structure. In some embodiments, the optical waveguide structure includes a semiconductor waveguide having a waveguide ridge, and a heater. The waveguide ridge may have a varying dopant concentration across its cross-section. The heater may include a first contact and a second contact, and the waveguide structure may include a conductive path from the first contact to the second contact, the conductive path extending through a doped portion of the waveguide ridge. Structure de guide d'ondes optiques. Dans certains modes de réalisation, la structure de guide d'ondes optiques comprend un guide d'ondes semi-conducteur ayant une nervure de guide d'ondes, et un dispositif de chauffage. La nervure du guide d'ondes peut avoir une concentration variable de dopant sur toute sa section transversale. Le dispositif de chauffage peut comprendre un premier contact et un second contact, et la structure de guide d'ondes peut comprendre un trajet conducteur du premier contact au second contact, le trajet conducteur s'étendant à travers une partie dopée de la nervure de guide d'ondes.
