Abstract
Chirped gratings with very broad reflection bandwidths up to 44nm and high reflectivity have been produced holographically in boron-codoped and standard telecommunications fibres which have been hydrogen-soaked . A 2nm wide transmission band has been produced within the broad refl ection band by use of an amplitude mask during grating exposure.
