摘要：

The spontaneous emission spectra and lasing characteristics of long-wavelength (13-mu m) quantum-dot lasers are studied. It is found experimentally that nonradiative recombination can dominate the room-temperature efficiency and limit threshold. By describing the quantum-dot spectral emission as due to energy levels of a two-dimensional harmonic oscillator, rate equations are developed to account for the temperature-dependent spontaneous and lasing characteristics.
