    Project Details


    To meet the continuously increasing need for progressively higher data transmission rates on the internet, faster signal modulation of the underlying semiconductor lasers or LEDs is required. High modulation bandwidth is a key quantity for the realization of high-speed data optical components, as it limits the maximum possible data rate. Recent developments in nanotechnology allow fabrication of new device types for lasers and LEDs with quantum dots embedded in optical microcavities which have the potential to outperform current devices. The nanolasers and nanoLEDs belong to this class of future optical communication devices. Conventional analysis methodology needs to be reassessed based on more realistic models which are appropriate for this type of semiconductor quantum dot based devices. The project will be carried out at DTU Fotonik which is involved in several projects in the field of micro- and nanostructured materials. This gives access to experimental results on devices as well as inside knowledge on technological developments. DTU Nanotech is also a partner and will contribute to this project.
