Broadband amplifier and high performance tunable laser with an extinction ratio of higher than 60 dB using bismuth oxide-based erbium-doped fiber

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...

Description
Summary: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 throughout the entire tuning range, the measured FWHM of laser lines are measured to be 0.09nm. In addition, the common amplification parameters are measured and studied in detail for various pumping configurations.
