LD04 – Modeling carrier transport in mid-infrared VCSELs with type-II superlattices and tunnel junctions

Torrelli V., Montoya J. A. G., Tibaldi A., Debernardi P., Simaz A., Belkin M. A., Goano M., Bertazzi F.

Vertical-cavity surface-emitting lasers are promising light sources for sensing and spectroscopy applications in the midinfrared 3 ÷4 µm spectral region. A type-II superlattice active region is used for carrier injection and confinement, while a buried tunnel junction defines a current aperture, decreasing the series resistivity. Highly nanostructured to optimize device performance, mid-infrared VCSELs pose modeling […]
