    Abstract

    We achieved the first demonstration of a wavelength-tunable mode-locked fiber laser in the L-band using allpolarization maintaining (all-PM) nonlinear polarization rotation (NPR). The all-PM configured laser features excellent repeatability and reliability. By increasing the pump power from 82.5 mW to 135 mW, a center wavelength-tunning from 1576.2 nm to 1592.2 nm is obtained. This non-mechanical tunning mechanism opens new possibilities for L-band wavelength-tunable lasers and their applications.
