Abstract
The photoinduced formation of Bragg gratings in optical fibres is expl ained as a consequence of convective instability. Close analogy is emp hasized between this phenomenon and the photoinduced second harmonic g eneration in optical fibres. The observed grating formation is interpr eted as amplification of very low frequency noise. Predictions concern ing the transient processes are made which could be checked experiment ally.
