9 December 201440nm tunable multi-wavelength fiber laser
A Brillouin-Erbium multi-wavelength tunable fiber laser at C-band is demostrated. A 10 km long singlemode
fiber(SMF), a 6 m long Erbium-doped fiber, two couplers, a wavelength division multiplexer, a isolator, an
optical circulator, a 980nm pump laser and a narrow linewidth tunable laser are included in the structure. A segment
of 10 km-long single-mode fiber (SMF) between the two ports of a 1×2 coupler is used as Brillouin gain. Ebiumdoped
fiber amplifier（EDFA） consists of a segment of 6m er-doped fiber pumped by 980nm laser dioder . A
narrow linewidth tunable laser from 1527 to 1607 nm as Brillouin bump, At the Brillouin pump power of 8mW and
the 980 nm pump power of 400 mw, 16 output channels with 0.08 nm spacing and tuning range of 40 nm from 1527
nm to 1567 nm are achieved. We realize the tunable output of wavelength by adjusting the 980 nm pump power and
the Brillouin pump wavelength. Stability of the multiwavelength fiber laser is also observed.
