We demonstrate the formation of complete pieces of high refractive-index three-dimensional inverse woodpile photonic crystals by a simple and inexpensive sol-gel process. A mixture of the titanium dioxide precursor and the silica dioxide precursor was infiltrated multiple times into a polymeric template produced by two-photon polymerization to improve the mechanical properties of the inverse structure. After removal of the polymer template, transparent inverse photonic crystals with a… CONTINUE READING
