Abstract

We report a reusable photonic structure using the 25 nm thin and discrete titanium dioxide (TiO2) layer deposited on one dimensional (1D) quartz grating to induce single mode lasing from variety of states of gain medium. Optically thick solid and liquid gains were used to reveal single mode lasing with reliable performance. The simulation showed that the DFB mode was obtained by the thin TiO2 layer and could be tuned by changing the superstrate refractive index.
