METHOD FOR PRODUCING A THREE-DIMENSIONAL PHOTONIC CRYSTAL USING A DOUBLE INVERSION TECHNIQUE

摘要

The invention relates to a method for producing a three-dimensional photoniccrystal comprised of a material with a high refractive index. To this end, aphotonic crystal is firstly provided, which is comprised of a polymer andempty interstitial lattice sites are provided through the surface thereof. Anetwork made of filling material is formed by introducing this fillingmaterial into the interstitial lattice sites. After removing the polymer,cavities result in the network formed from this filling material. The materialwith a high refractive index is introduced into these cavities whereby forminga structure therein that is made of the material with the high refractiveindex. After removing the filling material, the structure made of the materialwith the high refractive index remains and can be removed in the form of aphotonic crystal comprised of a material with a high refractive index. Thephotonic crystals produced according to the inventive method have completeband gaps in the area of telecommunications wavelengths.
