Three‐Dimensional Nanonetwork Assembled in a Photopolymerized Rod Array

Abstract

One‐ and two‐photon interferential patterning of photopolymerizable resin is demonstrated to lead to well‐defined two‐dimensional (2D) photonic crystal structures (which beat the diffraction limit) and also 3D nanonetworks, such as that shown in the Figure. The fiber‐like features are probably formed by a novel self‐assembly mechanism during drying. Applications in photonics are foreseen.
