Abstract

The use of metal-oxide-SiO2composite to sustain random lasing in ZnO thin films is proposed. It is shown that the presence of stripe pattern in the metal-oxide-SiO2composite is necessary to minimize lasing threshold and achieve directional emission. By controlling the concentration of the metal-oxide and stripe spacing, coherent lasing threshold and linewidth of ∼85 kW/cm2and ∼0.4 nm, respectively, can be obtained from mirrorless ZnO thin-film waveguide lasers.
