| Résumé | Theoretical and experimental results are described of several nonlinear optical structures and devices investigated by our group, that may potentially be usable for certain applications. Three groups of devices are addressed: a multiple quantum well switching device, a bistable semiconductor periodic multilayered structure and an optical harmonic mixer. Conclusions summarize results achieved up to date and point out some possible future paths to device concepts and their implementations, as well as potential applications in optical fiber communications, computing and signal processing. |
