Optical emission from individual strained indium arsenide (InAs)
islands buried in gallium arsenide (GaAs) was studied. At low
excitation power density, the spectra from these quantum dots consist
of a single line. At higher excitation power density, additional
emission lines appeared at both higher and lower energies, separated
from the main line by about 1 millielectron volt. At even higher
excitation power density, this set of lines was replaced by a broad
emission peaking below the original line. The splittings were an order
of magnitude smaller than the lowest single-electron or single-hole
excited state energies, indicating that the fine structure results from
few-particle interactions in the dot. Calculations of few-particle
effects give splittings of the observed magnitude.
