Longitudinal spatial characterisation of optical fibre erbium distributed feedback laser under the motion of steady magnetic field [PDF]

, 2014
The spatial sensitivity of an erbium doped optical fibre distributed feedback (DFB) laser to an external magnetic field is reported. Intrinsic birefringence of the laser cavity allows lasing in two orthogonal modes.
