Paper Abstract

For the first time we report spectral hole-burning with the width as small as (Gamma) equals 10 meV for semiconductor quantum dots of the size much smaller than the excitonic Bohr radius of the bulk material. The narrow nonlinear resonances found are typical of the structures prepared at the nucleation and normal growth precipitation stages. The saturation intensity on the order of <EQ 102 kW/cm2 registered for high-quality CdSe-doped glass is close to that for excitonic nonlinearity of CdSe monocrystalline films. The structures grown at the coalescence stage show only broad-band nonlinear absorption with a saturation intensity much higher than the proper bulk material.
