Multi-Photon Polymerization of Waveguide Structures Within Three-Dimensional Photonic Crystals

Abstract

Photonic crystals with line and point defects are desirable for application as photonic bandgap waveguides and optical cavities, respectively. Here such defects have been introduced into photonic crystals using a laser scanning confocal microscope. High-resolution 3D patterns are created inside the colloidal crystals (see Figure) via multi-photon polymerization.
