A New Synthetic Approach to Silicon Colloidal Photonic Crystals with a Novel Topology and an Omni-Directional Photonic Bandgap: Micromolding in Inverse Silica Opal (MISO)

A New Synthetic Approach to Silicon Colloidal Photonic Crystals with a Novel Topology and an Omni-Directional Photonic Bandgap: Micromolding in Inverse Silica Opal (MISO)

High refractive index contrast silicon colloidal photonic crystals having a different topology to those previously reported have been synthesized. A new process of colloidal‐crystal templating based on micromolding in inverse silica opals (MISO) is used (see Figure), and photonic crystals so built p...

Zusammenfassung:High refractive index contrast silicon colloidal photonic crystals having a different topology to those previously reported have been synthesized. A new process of colloidal‐crystal templating based on micromolding in inverse silica opals (MISO) is used (see Figure), and photonic crystals so built present a full photonic bandgap, as indicated by band structure calculations.
