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 .
