Abstract
A photonic band gap fiber structure is formed to include a plurality of filled air holes surrounding a solid silica core region. The material used to fill the air holes is chosen to exhibit an index of refraction that is greater than the index of the core, where the fill material refractive index is also adjustable as a function of temperature. Therefore, by adjusting the temperature of the PBG fiber, the dispersion characteristic of the propagating signal can be modified.
