Light Confinement in Quantum Dots

Abstract

A concept of light confinement in quantum dots due to diffraction of electromagnetic waves at the dot boundary is introduced. Possible manifestations of the phenomenon, such as depolarization shift of the exciton frequency polarization-dependent splitting of the gain band asymmetry off the absorption and gain spectra induced magnetization of quantum dots contribution to radiative lifetime, are discussed both for isolated quantum dots and quantum dot ensembles. We propose that the effect of light confinement should be properly addressed to optimize the design of optoelectronic devices involving quantum dots.
