—The bacterial cellulose (BC) secreted by Gluconacetobacter xylinus was explored as a novel scaffold material due to its unusual biocompatibility, light transmittance and material properties. The specific surface area of the frozen-dried BC sheet based on BET isotherm was 22.886 m 2 /g, and the porosity was around 90%. It is known by SEM graphs that(More)
A novel nanoscale polarizer based on surface plasmon polaritons is proposed by adding a silver nanoribbon to a traditional waveguide directional coupler. The novel polarizer can realize the polarization output of the TE mode with the characteristics of high extinction ratio and extremely compact dimension. The influences of the polarizer parameters(More)
