Abstract :
A novel all-fiber tunable multi-wavelength Raman fiber laser is achieved in a 50 km single-mode fiber connected to a multi-channel wavelength tunable component (MCWTC), i.e., a F–P cavity combined with a long-period fiber gratings based Mach–Zehnder interferometer, that is obtained by micro-processing. Raman amplified Rayleigh scattering feedback provides the mechanism for random lasing that is split to equidistance wavelengths and tuned continuously from 1553.9 to 1565.4 nm by the MCWTC.
