Abstract :
An Er-doped superfluorescent fibre source with enhanced mean-wavelength stability 2 ppm over the 0degC to 70degC range using chirped fibre grating is demonstrated. The effects of the temperature of the fibre, the pump power, the pump wavelength, the pump state of polarisation, and the feedback power have been considered and minimised with corresponding techniques.
