Spin lasers at 11.1 Gigahertz with potential for well over 100 gigahertz speed for the internet of tomorrow

Electrical engineers in Bochum have succeeded in developing a new concept for ultrafast semiconductor lasers. The researchers make clever use of the intrinsic angular momentum of electrons, called spin, to successfully break the previous speed barriers. The new spin lasers have the potential to achieve modulation frequencies of well above 100 GHz in future. This is a decisive step towards high-speed data transmission, e.g. for the Internet of tomorrow.

By injecting spin-polarized electrons in semiconductor based microlasers, modulation speeds can be reached that are far superior to any conventional lasers
