One-Dimensional Holey Fiber Is Highly Nonlinear
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...
