Erbium-doped superfluorescent fibre source with long period fibre grating wavelength stabilisation

摘要

The authors have reduced the temperature dependence of the mean wavelength of an erbium-doped superfluorescent fibre source to below 0.08 pm//spl deg/C (0.05 ppm//spl deg/C) using a long period fibre grating. This is greater than a 100-fold improvement on the 9.6 pm//spl deg/C (6.2 ppm//spl deg/C) intrinsic temperature dependence of the source.
