Subpicosecond soliton pulse formation from self-mode-locked erbium fibre laser using intensity dependent polarisation rotation

Abstract

Pulses as short as 765fs have been generated from an erbium doped, unidirectional, fibre ring laser, mode locked using the effect of intensity dependent polarisation rotation. The output from the laser exhibits all the characteristics of temporal and spectral instability expected from a periodically amplified soliton system when the amplification length is a significant fraction of the soliton period.
