Abstract

Two-photon polymerisation of photosensitive materials has emerged as a very promising technique for the fabrication of photonic crystals and devices. In this paper we present our investigations into the structuring by two-photon polymerisation of a new class of photosensitive sol-gel composites exhibiting ultra-low shrinkage. We particularly focus on two composites, the first containing a zirconium alkoxide and the second a nonlinear optical molecule. The three-dimensional photonic crystal structures fabricated using these materials demonstrate high resolution and clear band- stops in the near IR region.
