Abstract
By assembling polymer micro/nanowires, 3D wire structures for photonic integrations were fabricated, including a crossed structure, a crossed structure, and a parallelogram structure. Optical wave-guiding properties of the 3D wire structures were demonstrated with a measured insertion loss of , on average, at wavelength. Light can be transmitted vertically from one wire to another. Coupling efficiency between adjacent wires is tunable by changing the cross angle and the center-to-center distance.
