Low-loss and directional output ZnO thin-film ridge waveguide random lasers with MgO capped layer

Room-temperature ultraviolet lasing characteristics of ZnO thin-film ridge-waveguide random lasers with MgO capped layer fabricated on n-type s100d Si substrate are reported. It is demonstrated that highly directional emission from the facets of the random lasers can be achieved. Reduction of sca...
