【摘要】 A tunable dual-wavelength fiber Bragg grating(FBG)laser based on a distributed feedback(DFB)laser injection is proposed and experimentally demonstrated.The wavelength spacing can be tuned by adjusting the operation temperature of the DFB laser.When the DFB works at 25℃,a dual-wavelength simultaneous oscillation at 1 549.67 nm and1 553.44 nm with wavelength spacing of 3.77 nm is achieved.Our experimental results demonstrate the new concept of dual-wavelength lasing with a DFB laser injection and the technical feasibility.
