Abstract
A novel method to suppress noise in a high harmonic mode-locked erbium fibre laser is proposed and realised for the first time, dithering th e cavity length at a kilobertz rate. This method makes only one superm ode in the laser dominant and suppresses the others. A fibre laser so stabilised has enabled 2.5 Gbit/s soliton transmission over 205 km fib re remaining error free for 100 min, and in a recirculating loop achie ving a 10(-9) bit error rate at 12 000 km, respectively.
