| Abstract: | By means of high-temperature physical drawing, glasses can be directly drawn into subwavelength-or nanometer-diameter fibers. As-fabricated nanofibers show excellent diameter uniformity and surface smoothness for low-loss optical wave guiding, and may exhibit a series of interesting properties such as tight optical confinement, evanescent guidance and high waveguide dispersion. These fibers provide promising building blocks for photonic applications in optical communications, |
