Ultrafast photonic crystal nanocavity lasers and, optical switches

摘要

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 fJ 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.
