The surface morphology of ZnO films at different annealing temperatures and the performance of polymer solar cells (PSCs) with ZnO as the electron transport layer are studied. The low temperature sol-gel processed ZnO film has smoother surface than that i
The visibility in magnetostrictive fiber-optic interferometric sensors using a Gaussian laser beam is analyzed. It is shown that the conventional Gaussian laser beam has little influence on the visibility. The visibility depends strongly on the input stat
A filter-less frequency doubling generator with tunable phase shift based on dual-polarization modulation is proposed and analyzed. The setup is composed with a continuous-wave laser, a dual-polarization Mach-Zehnder modulator and a linear polarizer follo
