Abstract
The design, fabrication, and characterization of an electrically injected quantum-dot photonic crystal microcavity light source are described. The optical gain in the -based device is provided by self-organized InGaAs quantum dots with ground-state room-temperature emission at . The carriers are injected directly into the photonic crystal microcavity, which contains dots, avoiding surface state recombination in the photonic crystal pattern. The spectral characteristics of a single-defect photonic crystal microcavity show a single broad microcavity resonance. The output power is of the order of a few tens of nanowatts.
