Faster Internet with surface-emitting lasers?

Keywords:surface-emitting laser  high-speed laser  conventional lasers 

The next step for the Chalmers researchers is to modify the design and refine ways to control the laser, to increase speed and reduce power consumption even further.

"We strive to meet market demand ten years from now," Larsson said, estimating that by 2020, the industry will need energy-efficient cables that can handle 100Gbit/s per channel.

The research is being conducted at the Chalmers research centre FORCE and is funded by the Swedish Foundation for Strategic Research, SSF and the EU through the project VISIT. Participating companies in the European project are IQE Europe (UK), VI Systems (Germany) and Intel (Ireland). Informal project partners are Tyco Electronics and Ericsson (Sweden). The findings are published in Electronics Letters from IEEE Explore.

Anders Larsson: Each wafer contains up to 1,00 000 laser chips. The surface emitting lasers can both be fabricated and tested before we cut the wafer into chips.
