A broadband light source with an output of 150 mW at 1536 nm is constructed by using an erbium-doped power amplifier coupled to an erbium-doped superfluorescent fibre source. A nearly shot-noise-limited sensitivity of -161 dB and a dynamic range of 54 dB are achieved with an optical low coherence reflector using this source.<<ETX>>
A 59.1 GHz train of 2.2 ps solitons with low phase noise (<5*10/sup -5/) is generated by a novel, passive, all optical fibre source. The technique is based on transformation of a dual frequency beat signal generated by a 16 kHz linewidth erbium fibre DBR laser having a selectable and highly stable frequency separation, into a soliton train in a comblike dispersion profiled fibre, a novel fibre...
