CA 2579846

An integrated circuit may include at least one active optical device including a superlattice including a plurality of stacked groups of layers. Each group of layers of the superlattice may include a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and an energy band-modifying layer thereon. The energy-band modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions. The integrated circuit may further include a waveguide coupled to the at least one active optical device.

L'invention porte sur un circuit intégré qui peut inclure au moins un dispositif optique actif comprenant un super-réseau comportant une pluralité de groupes de couches empilés. Chaque groupe de couches du super-réseau peut comprendre une pluralité de monocouches semiconductrices de base empilées définissant une partie semiconductrice de base, et une couche modificatrice de bande d'énergie déposée sur ladite partie. La couche modificatrice de bande d'énergie peut comprendre au moins une monocouche non semiconductrice contrainte à l'intérieur d'un réseau cristallin de parties semiconductrices de base adjacentes. Le circuit intégré de l'invention peut en outre comprendre un guide d'ondes couplé au dispositif optique actif précité.
