Volume 2 Issue 11, November 2006
Following a flurry of activity in the 1990s, there is now a resurgence of interest in optical solitons: three papers in this issue present diverse insights into their manipulation, behaviour and potential practical use. First, Marco Peccianti and colleagues show how to control the path of spatial solitons travelling through anematic liquid crystal by electrically altering the refractive index of different regions of the material. Carmel Rotschild and colleagues report an extremely long-range interaction between spatial solitons — which usually only interact when they're less than a few beam widths apart — travelling within a heat-sensitive nonlinear medium. And finally, Joe Mok and colleagues demonstrate the ability to tune the speed of gap solitons, slowing them to a sixth of the speed of light in vacuum by launching them near the band edge of a fibre Bragg grating.
