Abstract
A method is provided for making a photonic band gap fiber including the steps of etching a preform and then drawing the preform into a photonic band gap fiber. Glass tubes are bundled and then formed into a photonic crystal perform having a number of passageways by reducing the cross-section of the bundle. One of the passageways is enlarged by flowing an etchant through it. After cleaning, the band gap fiber is made from the etched photonic preform, for example, by drawing.
