This investigation and those of other workers indicate that longitudinal fibre gratings with potential as Bragg reflectors can be written optically with guided powers of a few milliwatts. The observations reported here were made using a HeNe laser and demonstrate that the photosensitivity of germanium doped silica is not very frequency dependent. An analysis is made of the energy considerations underlying grating formation and it is concluded that about 1 MJ mole-1 is scattered or absorbed in the core of a fibre when a grating is formed.
