Abstract
We analyze a self-assembled quantum-dot laser where lasing levels are pumped purely through Auger carrier capture. Analysis shows that Auger carrier capture and Auger transport of carriers between quantum dots can provide effective laser pumping and fast modulation at least up to 10 GHz. Auger carrier transport decreases spectral hole burning, whic h together with dot-barrier hole burning can damp relaxation oscillati ons. (C) 1998 An American Institute of Physics.
