Nanocavity lasers exceed 100 GHz modulation speeds.

The article reports that photonic-crystal nanocavity lasers could go beyond the modulation speed of 100 gegahertz, as demonstrated by the researchers at Stanford University in Palto Alto, California. According to Hatice Altug of the Stanford research, the observed speeds are limited by the response time of the detector. The lasers could provide high-quality photonic-crystal structures due to its advances in semiconductor fabrication and crystal growth.
