    • CdS nanowires were synthesized using gold nanoclusters (Ted Pella, Inc., Redding, CA) as catalysts, and either a single-source molecular precursor (cadmium diethyldithiocarbamate, Lorad Chemical Co., St. Petersburg, FL) or laser ablation of a solid CdS target as a reactant source. Bent nanowires were prepared by raising the growth temperature by 40°C above the optimal value for purely axial growth. An upper bound for the diameter variation, ΔD, in the nanowire waveguides is ca. 1 nm over 10 μm length L, giving ΔD/L = 0.0001.

    • Studies suggest that modulation of the temperature or pressure during growth can yield abrupt bends along the nanowire axis in a controlled manner (Z. Zhong, C. Yang, and C. M. L., unpublished data).

    • -2. SOM images were recorded by determining the intensity at the nanowire end from a series of PL images, which were obtained by scanning the sample beneath the laser spot. The resolution in these experiments, 1 μm, was determined by the x-y sample scanning stage.

    • 2 correspond to the end intensity recorded with the laser at the two different positions along the waveguide. In this manner (Figure S1), the loss due to a bend or junction was estimated by comparing the loss observed in two segments of equal length along the waveguide: one along a straight section and the other containing the bend or junction.

    • note
    • Devices were fabricated on a heavily doped Si substrate, which serves as the lower electrode, with a thermal oxide layer. The nanowire is deposited on the oxide, covered with a cross-linked poly(methyl methacrylate) (PMMA) layer, and then the Au top electrode is patterned by electron-beam lithography (EBL).
