Contents 1. Introduction
Organic-inorganic hybrid polymers have been demonstrated to be superior materials for multi-photon fabrication of functional miniaturised photonic structures [1],[2]. The incorporation of unique emission-tunable nanocrystal quantum dots (QDs) can transform the plane polymer into a multi-functional active medium thus opening various possibilities for achieving novel active photonic devices. In this paper, we demonstrate the functionalisation of the organic-inorganic polymer, namely Ormocer, by lead-based core-shell QDs to achieve both high nonlinearity and emission in the technically important telecommunication region. It has been shown through the Z-Scan measurement that the nanocomposites possess an ultra-high third-order nonlinearity. In the meantime, 3D photonic crystals (PCs) with stop gaps matching the emission of QDs have been successfully fabricated in the modified polymer using the two-photon polymerisation (2PP) technique.
