摘　　要：A widely tunable high precision chaotic fiber laser is proposed and experimentally demonstrated.A tunable fiber Bragg grating(TFBG) filter is used as a tuning element to determine the turning range from 1533 nm to 1558 nm with a linewidth of 0.5 nm at any wavelength.The wide tuning range is capable of supporting 32 wavelength-division multiplexing(WDM) channels with 100 GHz channel spacing.All single wavelengths are found to be chaotic with 10 GHz bandwidth.The full width at half maximum(FWHM) of the chaotic correlation curve of the different wavelengths is on a picosecond time scale,thereby offering millimeter spatial resolution in WDM detection.A widely tunable high precision chaotic fiber laser is proposed and experimentally demonstrated. A tunable fiber Bragg grating （TFBG） filter is used as a tuning element to determine the turning range from 1533 nm to 1558 nm with a linewidth of 0.5 nm at any wavelength. The wide tuning range is capable of supporting 32 wavelength-division mul- tiplexing （WDM） channels with 100 GHz channel spacing. All single wavelengths are found to be chaotic with 10 GHz bandwidth. The full width at half maximum （FWHM） of the chaotic correlation curve of the different wave- lengths is on a picosecond time scale, thereby offering millimeter spatial resolution in WDM detection.
