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...

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
scattering loss inside the random cavities can also be obtained. In addition, the improvement in the
efficiency of the lasing characteristics of the random lasers by optical feedback is studied. |
