Modeling room-temperature lasing spectra of 1.3-mum self-assembled InAs/GaAs quantum-dot lasers: Homogeneous broadening of optical gain under current injection

The injection current dependence of room-temperature lasing spectra of a 1.3-mum self-assembled InAs/GaAs quantum dot laser is studied both experimentally and theoretically. The unique current dependence is explained by numerical simulation based on the quantum dot theory.
