| Abstract: | In this demonstration, we propose and experimentally investigate a widely C + L band wavelength-tunable fiber ring laser in continuous-wave (CW) tuning based on a hybrid semiconductor optical amplifier (SOA) and erbium-doped fiber amplifier (EDFA) in a serial scheme. When a hybrid first-stage SOA and second-stage EDFA is used inside ring cavity, the effectively amplification range can be extended from C-band to L-band. Here, the proposed laser features wide wavelength-tuning range, high output power, and high side-mode suppression ratio (SMSR). In addition, a tunable range over 91.5 nm (from 1518.5 to 1610.0 nm) has been achieved. |
