摘要: A wavelength-tunable superfluorescent fibre source with an erbium-doped amplifier was constructed to reduce the jaggedness in low coherence reflectometry. This capable of tuning narrowband superfluorescence (~1 nm FWHM) over a 32 range output 4.3 dBm. The signal averaging which resulted from wavelength this efficiently reduced jagged fluctuation Rayleigh backscattering profile ± 1 dB. advantage conventional smoothing is also discussed
