Three-dimensional photonic crystal templates fabricated in polymer by single-step laser exposure through a 2D diffractive optical element have been inverted in silica to provide robust structures with strong photonic stopbands in the telecom band.
A single laser exposure method of fabricating three-dimensional polymer photonic crystal having large number of layers has been demonstrated using a novel multi-layer diffractive optical element. Strong photonic stopbands are reported in the telecom band.
