February 15, 2010... 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 °c, concurrently with record performance: single-mode (>30dB SMSR) power of >1mW up to 100°C (>2mW at room temperature) and 10Gbps modulation and transmission over 10-km single mode fiber with BER <10–11 up to 100°C with <1-dB power penalty.

The researchers contend that these performances allow industrial partners to address previously established standards and pursue commercialization. The researchers also note that the development puts the emphasis on low-cost, intelligent and scalable networks ranging from metropolitan and local area networks (LANs) to access networks such as fiber-to-the-home (FTTH) and passive optical networks (PONs).
