Stabilising er fibre soliton laser with pulse phase locking

A stabilisation scheme for a mode-locked erbium fibre laser which relies on locking the pulse phase with that of the drive source is reported. Using this scheme, the first bit-error-rate (BER) measurement on such a laser has been demonstrated. Stable error free operation at 2Gbit/s and a received power of 26dBm has been observed over a period of >0.5h showing the potential suitability of the laser as a transmission source.
