| Abstract(in English) | Assessment of optical gain in as-grown SiO_2 thin film containing silicon (Si) and Germanium (Ge) nanocrystals, grown by rf-sputtering, by applying the variable stripe length (VSL) method, is reported. The optical gain in the thin film is demonstrated at 400 nm, at which the film shows photoluminescence peak. The analysis of the experimental data, based on one dimensional amplifier model, extracts the gain value of 4.3 cm^<-1> for a 738 nm thick film, when excited by a continuous wave 325 nm wavelength He-Cd laser. |
