Holography for one-step fabrication of three-dimensional metallodielectric photonic crystals with a single continuous wavelength laser beam

摘要

A single-beam holographic method for one-step fabrication of three-dimensional (3D) metallodielectric photonic crystals is demonstrated using a 632.8 nm He-Ne laser. A top-cut triangular prism is used to split an incident plane wave into four beams and then to combine them to form a 3D interference pattern. A silver halide holographic plate is used to record the interference pattern and then a 3D structure with embedded Ag particles is created. A strongly damping band around 1400 nm is observed in the transmission spectrum of this 3D structure.
