Layout of the full C-band tunable mode-locked polarization-maintaining fiber laser: (a) optical layout of the laser cavity of the C-band tunable mode-locked laser. C: fiber collimator. BPF: bandpass filter, WDM: wavelength multiplexer, Pump LD: pump laser diode. (b) Transmission curve of the bandpass filter versus the incidence angle. Red dots indicate the measured center wavelength of the mode-locked laser versus the incidence angle.
