ABSTRACT
Index-guided two-dimensional (2D) optical waveguides are numerically studied to investigate propagation properties of guided optical waves. The 2D optical waveguide consists of a dielectric thin film sandwiched between two semi-infinite metals. We demonstrate that vertically localized 2D optical waves can be laterally confined and guided by index guiding when the dielectric film has a high-refractive-index core and claddings of a lower index. The index guiding provides good optical power transmittance, otherwise optical power is rapidly attenuated due to lateral beam divergence.

    Chiral sculptured thin films, which contain amorphous silicon screws with a fiberlike fine structure, were grown by ion-beam-assisted glancing-angle deposition at room temperature. The thin films were postgrowth annealed in the temperature range from 400 to 1000 °C. Raman spectroscopy and...

    La0.7Ca0.3MnO3 (LCMO) films were prepared by a chemical solution deposition method on a Pt/Si substrate. Reversible resistance switching by electric pulses is observed in Ag/LCMO/Pt sandwich structures. This R switching behavior shows fatigue with time and applied pulse number. The voltage...

    The characteristics of nitrided HfO2 films suggest that the diffusion of Si from the Si substrate to the film surface is induced by annealing in an NH3 ambient and that the incorporation of N is closely related to the diffusion of Si. Changes in the core-level energy state of the N 1s peaks of...

    LiMn2O4 thin films with three-dimensional (3D) structure were prepared by the sol–gel method. Polystyrene beads (300 nm) were dispersed in the form of monolayers on Pt/Ti/SiO2/Si substrates, which were then used as templates for fabricating three-dimensionally ordered electrodes. A...
