One-Dimensional Holey Fiber Is Highly Nonlinear

Unique structure avoids deformations common with other holey fibers.

Breck Hitz, Senior Technical Editor

Typically, holey fibers are composed of glass, with a microstructure of tiny airholes surrounding the core. Several years ago, scientists at the University of Southampton in the UK demonstrated that holey fibers also can be constructed from two types of glass, with the lower-index glass substituting for the airholes in the microstructure. They called the fibers SOHO, short for solid holey. Now, they have shown that the SOHO technology enables creation of one-dimensional holey fibers, which may be more useful than two-dimensional fibers for generating nonlinear effects. Figure 1. In a 2-D...Read full article

    glass
    A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
