Abstract :
A novel technique for controlling the bandwidth of a fibre Brillouin amplifier is proposed and demonstrated. By using a frequency-modulated pump laser, in this case an external-cavity semiconductor laser, we have increased the bandwidth of useful gain by more than one order of magnitude. The scheme can be used to tailor the gain characteristics of fibre Brillouin amplifiers to
