Patent

CA 2235179

A DFB laser is provided with a top electrode divided symmetrically intotwo or three in-line separate elements through which a bias current is applied with a symmetrical distribution and through which a modulation current is applied in push-pull with a temporal asymmetry.

L'invention est un laser à réaction répartie doté d'une électrode supérieure qui est divisée symétriquement en deux ou trois éléments séparés alignés dans lesquels passe un courant de polarisation à distribution symétrique, ainsi qu'un courant de modulation injecté en montage symétrique avec une asymétrie temporelle.
