25_20b/2013Nanowire Heterostructures: Embedded Branch-Like Organic/Metal Nanowire Heterostructures: Liquid-Phase Synthesis, Efficient Photon-Plasmon Coupling, and Optical Signal Manipulation (Adv. Mater. 20/2013)

Organic/metal nanowire heterostructures are prepared by embedding Ag nanowire branches in organic microwire trunks during the self-assembly in liquid phase. The formation of exciton polaritons in organic wire under the excitation greatly improves the plasmon launch efficiency due to the direct photon-plasmon coupling. The light signals inputted from the organic waveguide can be selectively out-coupled to the predetermined subwavelength Ag nanowires. These organic/metal nanowire heterostructures are potentially applied in integrated photonic circuits as underlying optical multiplexers. Further details can be found in the article by Jiannian Yao, Yong Sheng Zhao, and co-workers on page 2784.
