Hj. Patrick et al., ERBIUM-DOPED SUPERFLUORESCENT FIBER SOURCE WITH LONG-PERIOD FIBER GRATING WAVELENGTH STABILIZATION, Electronics Letters, 33(24), 1997, pp. 2061-2063
The authors have reduced the temperature dependence of the mean wavele
ngth of an erbium-doped superfluorescent fibre source to below 0.08p,m
/degrees C (0.05ppm/degrees C) using a long period fibre grating. This
is greater than a 100-fold improvement on the 9.6pm/degrees C (6.2ppm
/degrees C) intrinsic temperature dependence of the source.
