A process for the preparation of a photonic crystal and three-dimensional photonic crystal

摘要

The invention relates to a method for the manufacture of a photonic crystal, in which, in a substrate (11) pores (10, 10 '') are produced, this having at least one of the substrate material different material to be filled and, finally, the substrate material is removed at least partially. The present invention also relates to a three-dimensional photonic crystal having a periodically arranged columnar structure (31 ''), which at least partially of metal or a metal alloy, wherein the columns (32'') in a longitudinal direction changing, in particular periodically changing, diameter. As a result, cost effective three-dimensional photonic crystals can be produced, which, for example, for ir - maintenance or air can be inserted in the gas analysers.
