Metallic nanostructure arrays have been highlighted by their tremendously promising applications, such as biosensors, light harvesting, and fluorescence enhancement. To reach the aim of obtaining an inexpensive gold elliptic nanocavity array (GENA) biosensor, which has high refractive index sensitivity, the two-photon nanolithography, with the advantages of high resolution, low cost, time-saving,...
Two-dimensional in-phase coherently coupled vertical cavity surface emitting laser (VCSEL) array with high beam quality was fabricated by proton implantation. Indium–tin–oxide (ITO) current spreading layer was employed to improve the uniformity of the injection current. This makes a coherent array to operate in in-phase mode even in a relatively larger scale. The appropriate thickness of ITO current...
