Abstract
We report on the third-order optical nonlinearity of the e 1 -e 2 intersubband transition in GaN-AlN quantum wells and the s-p z intraband transition in GaN-AlN quantum dots, both of them in the spectral region around 1.5 mum. The results in terms of third-order susceptibility, together with the ultrafast nature of the nonlinear response, render these GaN-AlN nanostructures particularly suitable for optical switching and wavelength conversion applications.
