A Bi 2O 3-based erbium-doped fiber (Bi-EDF) ring laser with a 70nm tunable range is demonstrated with a 49cm long Bi-EDF in which tuning range can be extended to larger than 100nm using an optical switch to alter the length of Bi-EDF in the laser cavity. With an extinction ratio of better than 60dB...
