Subwavelength-diameter silica wires for microscale optical components, at SPIE Photonics West 2005 Conference (San Jose, CA), Monday, January 24, 2005:
    Optical components built from structures that are tens of micrometers wide are playing a key role in current optical communication networks, optical sensors, and medical optical devices. The demand for improved performance, broader applications, and higher integration density, together with rapid advances in nanotechnology for electronics and optoelectronics, has spurred an effort to reduce the size of basic optical components. However, the miniaturization of optical components with subwavelength and nanometer-sized optical guiding structures through established fabrication methods is...

    Silica nanowires: manipulating light at the nanoscale, at Asia-Pacific Optical Communications 2007 (Wuhan, China), Saturday, November 3, 2007
    Can light be guided by a fiber whose diameter is much smaller than the wavelength of the light? Can we mold the flow of light on the micrometer scale so it wraps, say, around a hair? Until recently the answer to these questions was ‘no’. We developed a technique for drawing long, free-standing silica wires with diameters down to 20 nm that have a surface smoothness at the atomic level and a high uniformity of diameter. Light can be launched into these silica nanowires by optical evanescent coupling and the wires allow low-loss single-mode operation. They can be bent sharply, making it...
