A nanocomposite consisting of a photosensitive organic–inorganic hybrid polymer functionalized with PbS quantum dots has been developed using a sol–gel process. The uniformly dispersed nanocomposite exhibits ultrahigh third‐order non‐linearity (–3.2 × 10 −12 cm 2 W −1 ) because of the strong quantum confinement of small‐sized and narrowly distributed quantum dots. The non‐linear nanocomposite has been proven to be suitable for the fabrication of 3D micro/nano photonic devices using two‐photon polymerization. The fabricated photonic crystals show stop gaps with more than 60% suppression in transmission at the telecommunications wavelength region.
