The authors proposed a way to control the emission directionality of a stadium shaped microlaser by introducing an circular vacancy within the cavity. These investigations are implemented on the basis of polymer technology, which offers such benefits as flexibility, low cost, and compatibility with a wide range of materials. Experimental results are supported by ray simulations for a stadium with...
We report on the nonlinear optical properties of metal-dielectric Fabry-Perot resonators with broad spectral bandwidths in the visible, peak transmittance larger than 70 %, and a nonlinear absorptionup to 20times larger than bulk ZnO.
