Sammanfattning : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. LÄS MER

Sammanfattning : There is a need for lasers in the 370nm - 470nm spectrum (near ultraviolet - blue) for applications such as high storage, high resolution printers and biomedical applications. GaN-based vertical cavity surface emitting laser (VCSEL) is one interesting option due to the wide bandgap of the GaN and the 2D array capability and cost-effective production of VCSELs. LÄS MER
