Abstract :
The spontaneous length fluctuation of optical fibres caused by mechanical dissipation is analysed using a one-dimensional model based on the Fluctuation-Dissipation Theorem. Scale estimate shows evidence that the 1/f thermal noise originated from this fluctuation dominates at low frequencies in fibre interferometers and fibre cavities.
