Paper Abstract
An analysis of the effect of weak feedback on Bragg grating fibre laser output parameters is presented and a simple sensor
arrangement based on monitoring intensity fluctuations of a DFB fibre laser with a weak external reflector is considered.
Calculations suggest that it may be possible, under certain conditions, to resolve changes to the length of the external cavity
at close to the thermal noise limit. This introduces the possibility of achieving strain resolution in the sub-picostrain regime
in the low frequency domain where resolution of conventional fibre laser sensors is limited by 1/f noise.
