- Electroactive Tuning of Double-Layered Metamaterials Based on π-Conjugated Polymer Actuators
Tatsunosuke Matsui, Yuto Inose, David A. Powell and Ilya V. Shadrivov
Article first published online: 5 OCT 2015 | DOI: 10.1002/adom.201500276
Electroactive metadevices utilizing π-conjugated polymer are presented. Linear actuators made from heavily doped polypyrrole films are utilized to change the relative lateral position of two THz metasurfaces, and accordion-shaped origami actuators are used to change the distance between two microwave meta-atoms. In both cases significant tunability of the resonances is obtained by the application of a control voltage.

Chemical exfoliation is a simple and efficient method of preparing h-BN nanosheets. These nanolayers present a high solubility in water because of the hydroxylation of h-BN (OH-BNNS). Interestingly, the as-prepared OH-BNNSs exhibit excellent optical limiting properties with fascinating two-photon absorption. These nanosheets form a new and advanced optical material for sensitive optical components or for shielding human eyes from laser-induced damage.

Quadrature amplitude modulation is implemented in a single pixel imaging system, enabled by all-electronic metamaterial spatial light modulation. Experimental images at 3.2 THz are acquired to demonstrate the expected doubling of efficiency over previous single pixel systems. Results are deterministic and show no loss of image fidelity compared to nonquadrature methods.
- Characterization of a Mechanically Tunable Gyroid Photonic Crystal Inspired by the Butterfly Parides Sesostris

Article first published online: 25 SEP 2015 | DOI: 10.1002/adom.201500436
A mechanically tunable macroscale replica of the gyroid photonic crystal found in the Parides sesostris butterfly's wing scales is systematically characterized. By monitoring both photonic frequency changes and the distribution of stress fields within the compressed structure, electromagnetic transmission features are found and can be frequency-tuned and the structure only contains localized high stress fields when highly compressed.
- Surface-Energy-Driven Growth of ZnO Hexagonal Microtube Optical Resonators

Tubular ZnO microcavities with different wall thickness–radius ratios are synthesized by a novel surface-energy-driven micro/nanotube growth model, which is well interpreted by first-principles calculations. Emission spectra of such tubes reveal distinct whispering gallery and wave-guided interference fringes, which distinctly depend on the wall thickness–radius ratio, as verified by finite-element-method simulations.
