Ultrafast photonic crystal nanocavity lasers and, optical switches

We have recently demonstrated an ultrafast photonic crystal laser and cavity coupled laser array with modulation rates of 1THz at room temperature, a 20 GHz optical modulator with activation energies of 60 Q and a quantum dot photonic crystal laser with large signal modulation rates of 30GHz. These devices are enabled by the enhanced light-matter interaction in photonic crystals, and serve as the building blocks of on-optical information processing circuits.
