European Project Demonstrates Long-Wavelength VCSELs for Telecommunication Networks

The European project MOSEL,a three-year joint research program lead by CEA-Leti, developed efficient and reliable long-wavelength VCSELs (Vertical-Cavity Surface-Emitting Lasers). The project is to address the ever-growing demands for bandwidth in telecommunication networks. The researchers point out that, VCSEL technology offers low power consumption (from five to 10 times less than the conventional edge-emitting lasers) and can be manufactured in volume at low cost.

Six partners worked together on the three-year project to help commercialize long-wavelength vcsel technology. the project was lead by cea-leti (france) and included three academic partners: dtu fotonik (denmark), epfl (switzerland), and kth (sweden), and two industrial partners: alight technologies (denmark) and beamexpress (switzerland).

The project demonstrated error-free 10gbase-lr operation up to 100
