The Department of Engineering, Aarhus University, has received a grant from the Independent Research Fund Denmark to investigate nonlinear effects in semiconductor lasers – a stepping-stone to enable next generation higher-order modulation in fibre optic networks.
One of the properties of lasers is the reduced spectral distribution of their optical emission as compared to other light sources.
However, this laser ‘linewidth’ can be greatly influenced by the environmental conditions, which deteriorate their performance when used outside the research lab.
Now, Assistant Professor Nicolas Volet, who leads the Integrated Photonics group at Aarhus University (AU) has received a DKK 2.9 million grant from the Independent Research Fund Denmark for a new ambitious project, that aims at solving the linewidth issue of diode lasers.
This issue is known to be one of the limitations in the deployment of coherent higher-order
