Paper Abstract

We present a multiwavelength mode-locked fiber ring laser incorporating a semiconductor optical amplifier (SOA) and a Fabry-Perot semiconductor optical amplifier (FP-SOA). SOA is mode-locked by an injected external optical signal, act as loss modulator, and FP-SOA serves as a tunable comb filter. Our laser source can generate 19 synchronized wavelength channels with the extinction ratio of about 21 dB, each mode-locked at 10 GHz, and modelocked pulse width is about 40 ps. Oscillation wavelengths band and wavelength spacing can be tuned by adjusting bias current and a tunable optical delay line (ODL) or a temperature controller, respectively. Polarization insensitive devices ensure that the output power is rather stable.
