Three-Dimensional Nanonetwork Assembled in a Photopolymerized Rod Array



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.
