Two -Photon Polymerization of Defects in Photonic Crystals

For applications requiring a complete PBG, it is necessary to convert colloidal photonic crystals to higher refractive index structures that exhibit complete PBGs. To this end, self-assembled photonic crystals with embedded TPP features were replicated in silicon. The TPP features and colloidal crystal served as a template for the final structure---a silicon-air inverse opal (which may exhibit a complete PBG) with embedded air defects. Embedded planar defects in silicon colloidal photonic crystals were optically characterized and high resolution embedded air defects in silicon-air inverse opals were demonstrated, representing a major step forward in providing a platform for the utility of colloidal photonic crystals for PBG-based applications.
