Researchers at Ghent University - imec have developed nano-ridge surface-emitting lasers (NRSELs) epitaxially grown on 300 mm silicon wafers. This innovation leverages one-dimensional photonic crystal modes, enabling scalable, tunable surface emission.

The NRSEL design overcomes limitations of traditional VCSELs by integrating high-quality III-V materials directly on silicon, allowing for flexible emission wavelengths and reduced device complexity. This advancement is poised to enhance applications in telecommunications, LIDAR, and quantum technologies.
