Two-photon polymer laser writing in the photonic crystal

We report a technique for embedding submicrometer-scale polymer defects in the interior of self-organized two-dimensional photonic crystals by controlled two-photon induced polymerization. They demonstrate a rapid and flexible technique for optical fabrication by creating polymer features in registration with a photonic crystal. Polymer features were embedded in individual pores with a diameter of 100 nm by controlled photopolymerization under confocal optical microscopy. Spectrum measurements confirm that the photonic stop band limits the light propagation of the emission from the embedded polymer structures.
