Abstract :
The reflectivity of weak in-fibre gratings (a few percent reflectivity) written by an ArF laser illuminated phase mask can be dramatically enhanced (reaching ⩾95%) by subsequent exposure using a uniform ArF laser beam. This new effect offers the possibility of post-writing control of grating properties
